Camping App for Ipad for Astronomy and 4 additional Sketches

Another quick post about an app for Camping that I found that is free. I have modified it for making a loading list for my astronomy equipment and to make sure I have all of my cold weather gear with me. I found the app by a list serv I'm on for school, and here is what it looks like on a iPad (lower right corner).

After you open the app you come to this screen.

This screen allows you to create a new list and then to add items to it. Here is the one I started for my winter clothing. I usually don't forget anything on my cold weather clothing list but its nice to have a checklist.

Finally, here is a list with items I created so that I could have a checklist for when I am loading up my equipment. Getting into my mid to late forties now, I find at times I tend to forget one or two things (like my Telrad Riser which I hate not to have) so I started this list (its done now) with everything I have. I can click on the time and check it off when I have loaded it up. Its nice in middle age to start using lists!

Overall I like this app. You can add or subtract items and customize it for yourself. The camping stuff is a good way to plan if your staying overnight to make sure you everything you need there. I would rate this app a 4.5/5. It's nothing out of this world, but it gets the job done and the price is right, free.

Now, here are the last of my sketches from the other night on the 24th of February. I had time tonight to finish processing these and then to get them posted since its snowing hard and we are at 2 inches in 2 hours. Sure hope it lets up before the a.m. and they plow the roads or the commute to work will be a bear.

Observations done on February 24th, 2012 at Pit n Pole, Utah; Antoniadi I, 14" dob, 5mm, 7mm, 10mm Pentax XW and 14mm Pentax XW with Paracorr I.

Now, I secretly made this sketch for my friend Mat, because as he says, "NGC 2359 is becoming my favorite winter object much like the Swan in the summer." At least something close to that. I hope I did Thor's Helmet justice in the sketch.

While in Ursa Major I also sketched M106 so here is that sketch. The arms are brighter than they should be slightly.

Here is M82, Bode's Galaxy in Ursa Major. Pretty close to spot on how I saw it.

Finally, Messier 81 in Ursa Major. This also is pretty close to how it looked for me. One arm needs to be a touch fainter than the other. Other than that, I am really happy with this sketch. I finally am beginning to feel like I am starting to get close to what I am seeing in my sketches. That is a good feeling.


Observing Session February 24th, 2012 Pit n Pole

Well the weather predictions held true and Friday was just a knock out gorgeous day. After getting off work I went home, checked the oil and fluids, added some oil to the Pathfinder and then packed up to head out. We had decided on Pit n Pole because a storm had come through this week and based on my experience from the previous week at FR006, we feared the road could still be too muddy for my friends Mat and Jorge to get their cars down. However, I had another friend who headed out that way and he called and told me it wasn't muddy. Then I got pictures on Saturday and the site wasn't muddy, and the road wasn't as muddy but you'd still need a 4wd to get in and out safely. The Vernon site is wonderful, but like the Lakeside Utah site, if it snows or rains, it gets muddy. Vernon needs a solid week of good weather to dry out. So heading to the pit was a good decision.

After I got the Pathfinder loaded, something kept nagging me that I had forgot something. I found a new app for camping (I'll review that later this week) and had made a list of my telescope equipment and went through it one more time. The back of the car looked like I was missing something, but I think I have finally figured out how to load the back to conserve space. So I said good-bye to my son who had to go to work and drove off. About 6 miles into heading to Pit n Pole I saw my oil cap going flying off the spot I put it when I change or add oil and it flew out on the highway where it was instantly lost. Luckily the Pathfinder doesn't blow oil so off I went (and yes, I got a new oil cap for it).

Here are some images I took on the way out for the fun of it and too share. On the way out to the desert, either to Pit n Pole or to Vernon or other sites out there, one drives through several small, and I mean small, farming communities. Most are ranchers now but there is evidence that some have been around for a long time. Here is an old garage/shed that is next to a boarded up house (I'll get the house in March) and I just like the feeling this brings out. These are pretty common sites in the rural towns of Utah and gives Utah some of its character.

I have lived in Utah for about 19 years now, and I love the access to the wild here, but I fear that access is going to go away in time because of the continued growth in the region. I hope I'm wrong and a balance is found. Like any place though, Utah has its good points and its not so good points but the mountains are definitely one of the good points. I love the mountains in Utah and all that they bring in terms of recreation, especially hiking.

More mountains in the distance as I turn and head towards Pit n Pole on the old dirt road. Love the view!

Finally, sunsets at Pit n Pole are my favorite times as I have discussed. So peaceful . . . well, except for this night.

Mat actually beat me out to the Pit and when he arrived, a small boy scout troop was setting up two tents and had a truck and a trailer. Mat talked with them and they were really cool/nice and positioned their trailer to block their fire. He called and we talked and agree to go there. I called Jorge who I had told to go somewhere else so he came back. We set up in an observing area several hundred feet away and then after we got set up, we provided them with a private/public star party. I showed the scouts and their leaders M42, Venus, Jupiter, M65 & 66, Mars, NGC 2362 (my favorite open cluster) and I answered several questions they had. Mat showed them other goodies as well and it was quite fun. They stuck around from about 7:00p.m. to around 8:45p.m.

One of the things I did this last winter was to buy a Thousands Oaks Dew controller and to get some dew strips to stop the dew from ruining my views at the Pit. On the 17th they worked wonders. I took images tonight so I'll share those but these are not the final placement for the controller. I need it higher up to handle when I go to zenith. Fortunetly I never really needed this night as conditions were just terrific. No humidity, no frozen dew at all and the skies were magical, Antoniadi I all the way down low. Even Sirius only blinked about every 3 to 5 seconds and then it was only a very small flutter. Oh, and before showing the scouts stuff, I went to Sirius and nailed the Pup again. It is rather easy right now because it is so far away from Sirius. A dark site helps in the early evening also.

Here are my dew controllers. I went with the Thousands Oaks because of outstanding reviews and the fact I don't have that much dew to worry about in Utah so when I need them, it is usually one setting and I'm set to eliminate the frost. Others I've read get the DewBuster because it comes on when needed but I didn't want to pay the extra money. I have the money but I don't mind the inconvenience of adjusting to save some money.

Oh, before the dew stuff, I also got a new mat from Sam's Club for $15.99 I believe (might be $19.99). It's smaller and more padded then my last one so I really like it. I still would like to get a nice piece of carpet at some time but this pad works nicely. Yes, the area I set up in was dusty this night, but dry!

Here is the Thousand's Oak Controller. I may set it to connect where the Intelliscope goes or on the other side or I may just try to find a place on the upper OTA to place it. I'll wait until I have Carl Zambuto's new 14 inch mirror in since I'll have to do some counter weight adjustments or virtual counter weights since I'm losing six to seven pounds from the mirror. It's attached with a Velcro strap that goes around and laces through and then connects so it wasn't going anywhere.

Here are the dew straps for the Telrad, the finderscope and the eyepiece. Funny, the eyepiece works on both the 1 1/4 and my 2 inch pieces. I'm to the point I may drop the finder 9x50 since I use the 27mm Panoptic for finding a lot but sometimes on some objects, I just like see the big view through the finder scope.

This night I actually got quite a bit of work done. I need a bunch of Herschel items in Puppis to finish the 400 (just some spring galaxies now) and I got over 18 objects in Puppis. I am not going to share all as I haven't processed all the sketches but just the ones that I liked and that are done. I found that I was rather rusty at sketching open clusters so it took a while to get back into shape. These are the originals on the only thing I did was in GIMP to adjust the contrast to hid some pastel dust that got on the paper.

The first object was NGC 2467, an emission nebula and open cluster in Puppis, I have seen this one before and sketched it before but when I viewed it with the 27mm Panoptic, I wanted a wide field experience in the sketch. So here is the result. Click on it to make it larger. I loved the sketch when I was done, but unfortunately some pastel dust got on the black so that is showing up. There is meant to be nebulosity around the three stars in the center as I observed that and had it confirmed.

Here is NGC 2482 (these aren't necessarily in the order of observation. I got sick on Saturday and am still recovering and wanting to get this post up). Wide open cluster, loose and spread out. I'm getting into seeing what my eye makes of the shapes and I can see Yogi Bear or Snoopy with their noses facing to the left in this sketch.

The next object is NGC 2483. Another loose and spread out open cluster with about 20 or more members viewable of different magnitudes. This cluster I am calling the Cat Cluster because I definetly see a cat with its tail raided on the left side, its body stretched out in the center, and the head near the top with the two eyes and the nose. Anyway, some fun I guess.

This is NGC 2527 another loose and medium rich open cluster is Puppis. Please see my comments on the sketch by clicking on it to see all of them larger. I am calling this, after I sketched it and looked at it today, the Fireworks Cluster. The reason is that this cluster as sketched reminds me of the type of fireworks listed below. Now I need to research the type/name of this firework so can call it by that name officially.

Here is an image of the fireworks I mean. I see a resemblance, do you?

NGC 2571 an Open Cluster in Puppis.

After getting tired of open clusters and finishing off my hit list of them in Puppis, I knew I needed some galaxies in Ursa Major and by now The Great Bear was hanging high in the sky. So I turned the dob over their and went to work. Unfortunetly I thought I needed on of these pair, but in reality, I had already observed them. Man will I be glad when May 5 comes and I am done with classes for at least a year! I need to update my entries in my logs. Oh well, it was fun hopping and finding all of them. I even paid an old friend a visit this night and I am pretty happy with that sketch.

NGC 3756 and NGC 3738, spiral galaxies in Ursa Major. NGC 3756 is not edge on, its actually titled towards us but my view really showed it diffused. NGC 3718 was moderately large, had some structure to it and a brighter core region.

NGC 3733 was the next victim, and this is another spiral galaxy in Ursa Major. I used my 10mm Pentax XW on this and thought it brought out some rather good detail this night. Again, conditions were some of the best I have seen at the Pit of Dew (Pit n Pole) since last summer when I was there with Daniel Turner. The galaxy is a little brighter than I wanted it to be as it is actually a little fainter. I've been working with my layers and guess by the late time I was tried and not watching how much pastel I was putting on the paper. Brightening near the core, and overall I like this sketch.

This is probably my third favorite sketch of the night. The first one is coming next and the second was the emission nebula above. This is NGC 3718 and NGC 3729 both spiral galaxies in Ursa Major. NGC 3718 was roundish but showed just the hint of a tip especially at the southern end. Core region was bright and uneven. NGC 3728 was elongated and showed some brightening in the core region. A pretty pair to observe if you have a chance this spring.

NGC 3992 or Messier 109, a large Spiral Galaxy in Ursa Major. This is my favorite sketch of the night as I know I captured the detail I was observing in the eyepiece this night. Bright stellar nucleus, brighter core region and the hint of structure because of the variance in light observed. Just a terrific observation and this is making me think I need to re-sketch the Messier again (but after I get done with the five projects I have going.

I have others and I'll try to add some this week but in reality it will be next weekend as I have a lot to do this week. Hope you enjoyed sharing some of my observations and sketches. Look up at whatever turns your fancy!


Observing Session, February 17th, 2012 ??? on location

Well this last Friday was very cloudy during the day. I had planned to go observing and I was going to drive out to my new favorite location no matter what, in defiance of the weather. Skippy Astronomy, the National Weather Service locally and Clear Sky Clock (clicking on the cloud cover for details) all showed clearing that evening. I loaded up at 3:00p.m. and headed out to Vernon to get to 006 FR Site 1. Well, the drive out went well and as I turned right to get onto the main dirt road, the road was rather wet and though not really muddy, except on the sides of the road (the road is graded so water goes to the side) I began to wonder what conditions was going to be like when I got out to 006 FR (FR is Forest Road). Well, I got out to where I turned right and then I came to 006 FR and turned left. I hesitated at first because the road was snow covered and covered in what appeared to be mud. It looked like another vehicle had gone down the road and had left some ruts. I drove in and as I drove I could feel the Pathfinder slipping. I put it into 4WD and the slipping ended and as I went down I knew I had made a mistake. I decided to turn back and called my friend Mat to tell him to go to an alternate site at Pit n Pole. Mat suggested I just simply back up since there is no place to turn around in the road in the muddy conditions. I backed up and got out. Here are some images I took of the general area and of my tires after I got off 006 FR.

You can see the depth of the mud on my tires, not so deep but I had a lot of mud in my wheel wells and it took some time on Saturday to get a high speed wash to get it all out. Again, if your new, click on the picture or the sketch to see it in a larger format.

Another image showing that my foot board also got some decent mud (yes, not too bad, I've had my Pathfinder much muddier in the past).

Here is the road that you turn right on to get to 006 FR. Very passable but still muddy a little bit. The issue I see is that the sun wasn't able to melt the snow and dry the dirt before I got out there. Lesson on this observing location . . . IF it has rained or snowed don't go there if the Sun has been behind the clouds and hasn't dried out the road.

Sunset looking west. Compare the next two pictures with the images I took in January and you can see the amount of snow we've had the last month.

My favorite shot, looking south.

So I drove back to Pit n Pole, taking about 25 minutes to get there and when I got there, Mat was set up. I set up the XX14i and decided since I was at the Pit of Dew as I now called it, to set up my dew controller and dew straps for the finder, the Telrad, the eyepiece. I held off on the secondary because I am going to attach a secondary safety strap using dental floss, but more on that on another post. At that time I will attach the secondary dew strip at that time. I will take pictures of my dew set up next time I get out or as I set up the scope to do some maintenance work and put the dew equipment on permanently. I went with the Thousand Oaks controller and it worked like a charm! For the first time at the Pit n Pole or Pit of Dew, I had no dew impact my viewing the entire night. The scope did frost up pretty good but not my finder, Telrad or eyepieces! Yeah!!!!!

I had a hard time getting started this night and I have to admit that I was a little flustered because of what had happen at Vernon. That site is my primary site because of its lack of people, lack of shooters and most importantly the darkness of the sky. I started working that evening in Puppis and had a hard time getting to the first open cluster but I finally nailed it. I then worked and bagged several more open clusters but I wasn't in the mood to sketch them, so I didn't. I simply recorded my observations on my digital recorder and then moved on.

Later that evening I decided to take a break from the Herschel objects and I had grown tired of viewing so low in the sky, and I went to M42. Wonderful view as always. I then saw that Leo was up and I took off for Leo, getting a second wind and an idea. I had two goals in Leo. First is probably a fantasy but I have been trying for the Tidal Tail in NGC 3628 for a while now. This night I think and I stress, I THINK, I got a glimpse of it. Conditions had improved as the night went on and I captured a slight brightening in the eyepiece right off the left side of NGC 3628 in the right location to be the initial part of the Tidal Tail. In the observation I have to state that the first part of the Tail wasn't evident, this was a slightly brighter part that is a little farther off. See my poor man's sketch. I haven't counted this as I didn't have anyone come over and verify and I share it for the fun of it. To quote Carl Sagan, "Extraordinary claims require extraordinary evidence" of which, again, I have none as I had no one confirm it. Again, this could and probably is simply something my mind put in there because I want to see it, and I know where it is and I am willing to admit to that. However, the brightening was real to me and I have enough experience to know when something is on the verge of seeing. This sketch is based on the one in the field I did as the dew was bad and I couldn't work long before the dew impacted the paper. The tail is too bright to what I saw, I need to lessen it.

NGC 3628 is often called the Hamburger Galaxy or as I learned in looking things up on the galaxy, Sarah's Galaxy. I include that for a friend and hopefully he can share that with his daughter! Here is the sketch.

My next purpose was to get started on a project I have played with for sometime. I had a grand idea I would make it into a book but I think I am going to just post it here. The goal is to sketch some (not all) of some of the Messier objects from a dark site and then to sketch them again from my backyard and in light pollution. The purpose is to show others the impact of a dark site on observing and what can be seen. If there is a sketcher out there that wants to coordinate on this project with me, I'd love to do that. So instead of looking at more open clusters, I went looking at galaxies in Leo. Here are the sketches I made at the scope.

Here is the Leo Triplet using my 27mm Panoptic. An admission on the sketch. If you looked closely I put in the location where I saw the Tidal Tail but it wasn't visible in the 27mm Panoptic. Besides that I really like this sketch overall and was happy with the outcome. It's been a while since I sketched such bright objects!

NGC 3593 a spiral galaxy in Leo. Found just opposite of the Leo Triplet (M65, M66, NGC 3628). Elongated East to West (north in this sketch was labeled slightly too far to the left. It needs to be more to the right) with a brightening of the core and a stellar nucleus. Fun galaxy to observe and I enjoyed viewing these galaxies after chasing Herschel objects for 3 years now. It has trained the eye to see that much more detail.

Here is M105, NGC 3894 and NGC 3898 in Leo. M105 and NGC 3384 (the elliptical galaxies) had very bright cores and stellar nucleus. NGC 3389 (the spiral galaxy)had a brightening of the core but I could not make out a stellar nucleus. Fun trio to view as always.

Messier 95 showed well this night, one of the best views I have had of this galaxy. The bar was discernible with averted vision and that led to a ring like structure. A hint of one of the arms was there so I included that in the sketch. Very time sketching this one.

Messier 96 in this sketch. Probably my favorite sketch of the night as I felt I caught the detail the best and the star field. I did too many stars to be honest, as I am trying to stay with the main field stars so the sketch can be oriented better for those wanting to do that. Part of my growth I guess. I like how I captured the various brightness of the stars in this one.

So that is what I got done. I'll go back and sketch the open clusters in Puppis next winter. I just got tired of viewing them all and trying to sketch them that night was just not going to work well. I may try to do it when the moon comes up from home because the rest of this new moon week here is looking horrible for observing! Snow and clouds this week. It is the pits since this is the last new moon before Daylight Savings Time comes back again in March. That means a later start and not as much time at the scope unless I stay out later and/or camp. I hope this March, April and May brings good periods of clear skies to get in some spring observing as I haven't had much of that the last two years. Clear skies to you.


Observing at FR006 Site 1 south of Vernon Tonight

Well, the clouds look dominating right now, but the forecast is for clearing and for a mostly clear evening so I am going to head out to FR006 tonight to the first site (see my older post below for the location). Your welcome to come and join me if you want to risk it. I figure nothing risked means no reward and in the worst case, I simply have a nice ride out to a wonderful site this afternoon. I'm leaving around 3:00p.m. to give me plenty of time to set up. The weather here turns nasty after today though I do hope next Friday or Saturday is clear again (and I hope it clears tonight as all the weather places are saying).

In case you've forgotten and want some visuals. See a map and go south on Hwy 36. Just pass Vernon the road curves to the left and you see this sign:

There is a nice dirt road to the right and you need to turn on it (there is a paved one next to it, don't go on that one). Now drive onto the dirt road and proceed to drive down the dirt graded road, over 5 cattle guards for 5.0 miles. At the end of the road you'll come to this sign.

Turn right here toward Bennion Creek and Harker Creek and drive for 0.5 or 1/2 mile to Forest Road 006. It will be on your left and when you turn, you'll see this (yes, turn left at Forest Road 006).

It will look like this and there is another dirt road to your left, turn onto that dirt road which is FR006.

The marker just says 006 with FR on the bottom. You will now drive 0.9 or nine tenths of a mile down Forest Road 006 and on the left you'll spot a turn out with a bunch of juniper trees there. To the east just beyond the trees is a very old cattle trough and that area is wide open. This is the observing site. Pretty easy to get to and cars and mini-vans can handle this just fine. So even if you don't have a scope, come on out and enjoy a very dark sky with us!

Above it what it looks like from 006FR and below is what it will look like if you pull in past these juniper trees.


Final Exam for Astronomy 101 with Answers

Okay, not much observing is going on and the reason for that is partially the weather, its been cloudy and rain/snow mix (snow melts right away), and then I've been swamped with other responsibilities so I'm tired at night and thus haven't done much lunar or double observing this moon period. I was going to start posting on my lunar and double sessions but we'll have to wait til later this month I guess. I am hoping the 17th and 18th are good and right now the forecast is looking good for those dates, but it is far enough out we'll see what comes to pass. If the dates hold, I'll be out observing.

I am having trouble sleeping at times (the heat kicks on and I don't like to sleep in an area with warm air, it wakes me up) so I was browsing the web and I found this Final Exam from an Astronomy 101 class from 2007. It's long, 100 questions but they are all multiple choice and the test comes with an answer key. So IF your up to the challenge and want to test what you know about basic Astronomy related objects and topics, head over to this link and take the test! It's in Google Documents so you can download it if you want also (not my Google Documents). I'm not sure if the test will awaken me more, and make it to where I don't get the final two hours of sleep tonight or if it will put me back to sleep. Anyway, I just thought it is a fun thing to do. Enjoy!


Andromeda Galaxy (M31) Double Nucleus

Hubble Zooms in on Double Nucleus in Andromeda Galaxy

I had to go and pick up my new glasses tonight and after getting home around 8:00p.m. I went looking around the Web. I ended up at the Hubble site and at NASA and found this image taken by Hubble of the double nucleus of the galaxy Messier 31, M31 or the Andromeda Galaxy. In the center is a 100 million solar mass black hole and it is surrounded by relatively young blue mass stars in orbit around it and another older red mass group of stars caught in the black hole's gravity. From the NASA site:

The double nucleus is actually an elliptical ring of old reddish stars in orbit around the black hole but more distant than the blue stars. When the stars are at the farthest point in their orbit they move slower, like cars on a crowded freeway. This gives the illusion of a second nucleus.

Now what is cool about this image is it is the "sharpest visible light image ever made of the nucleus of an external galaxy." That to me is super cool! Next time I view M31 I will be sure to remember this image and think about what I am actually observing here. The other cool item is that Astronomers are using this and observations from the Milky Way to solve a question about massive star formation so close to a black hole. Again, from the NASA site we read:

The blue stars surrounding the black hole are no more than 200 million years old, and therefore must have formed near the black hole in an abrupt burst of star formation. Massive blue stars are so short-lived that they would not have enough time to migrate to the black hole if they were formed elsewhere.

Astronomers are trying to understand how apparently young stars were formed so deep inside the black hole’s gravitational grip and how they survive in an extreme environment.

The fact that young stars are also closely bound to the central black hole in our Milky Way galaxy suggests this may be a common phenomenon in spiral galaxies.

Music of Copland for Observing

Cassini-Huygens Liftoff

Well, this is another one of those reflection posts but this time I am going to keep it short. Tonight I took the night off from doing work, astronomy/observing stuff/ATM stuff or even being around my kids. I have to run and put gas in my car tonight but other than that I am just relaxing. One, no, though I love music, in many forms and styles and types, I find at times that I really enjoy classical music (new age like George Winston and William Ackerman and others also). My favorite composer is Aaron Copland because his music reaches me and touches my soul. I'll be 47 in a few months and I know I have fewer years ahead of me than behind me, and I've touches on that, but Copland's music just gives me hope, confidence and faith in the ability of the common people of this earth to prevail. So tonight I am going to simply share some of my favorite pieces that I relax, work to and that when alone, I observe to.

My favorite piece that Copland expounded upon is called The Promise of Living. The orchestral version is located at this link over on YouTube. Originally this was a piece in an opera I believe and is a choral piece. If you want to watch and hear the choral piece that link over at YouTube is located here. The orchestral piece is the most moving to me personally. The message of the choral pieces that working together, and sharing of what we having, of growing beyond ourselves and loving others though is a very strong message and humanistic. I guess though tonight it is the orchestral piece that moved me because it made me think of my father-in-law who passed away this last August. My children basically were watched over, served and loved by him until they went to school, and then because of work, he often dropped them off or picked them up. He was perhaps the most devoted man to his wife, the most caring, the most patient and the humblest man I have truly ever known. He worked, and from his work he shared what he created with others, his family, neighbors and others. He was a true Master in woodworking and he farmed for most of his life. When I was observing in the backyard, he always came out for about 15 minutes to look at what I was viewing and was amazed at what he saw. So listen to both, and you can decide which version you prefer. I like the orchestral one because I can make my own meaning from that version.

I thoroughly enjoy The Quiet City also for the reflective mood, and the hope that the super fast pace of our lives can slow down enough so that we who live in the cities or in suburbia can find some "Quiet Time." Here is the link to YouTube. For me while observing, both pieces provide me with a peace and an enjoyment of what I am observing, reminding me of my own smallness in this vast universe.

Fanfare for the Common Man came out in WWII and it was suggested that it be called Fanfare for the Common Solider. Copland nailed this by calling it for the Comman Man. One person commenting of this video makes an excellent connection with the music and the moon landings. Both were truly accomplished by the common man being behind the effort to get there. For that matter, I think our space program, our outreach, even our personal observing is to remind the common man of our place in the universe. I also think it inspires the common man and woman to be more than they are; the programs elevate us to our better nature. Here is the link for that video (forgive the aliens at the end, it is the only part I don't like). Also here is a link for a version that has several record recordings of Fanfare for the Common Man linked to the Shuttle and Apollo Program.

Now that I shared that, I could keep going and share my favorite hard rock, new age etc. music but I won't. I like observing with just the sounds of nature, I also like having music at times. Whatever you do, I hope you find ways to enjoy your time under the universe.
