SuperNova Found in Eridanus

Just in case your not aware, a new supernova has been found in the constellation Eridanus. Here is a copy of an AstroAlert posted on a local message board about this:

This is an AstroAlert from Sky & Telescope.

An 8th-magnitude nova was discovered on November 25, 2009, by Koichi Itagaki of Yamagata, Japan. The new star lies in northeastern Eridanus, 6.9° west-southwest of Rigel. In an e-mail sent late on the evening of November 28th, Sky & Telescope Senior Editor Alan MacRobert writes, "Just spotted the nova in my 10x50 binocs on their wooden shoulder frame. Barely visible through the bright moonlight at about mag 8.4."
The find was announced on CBET 2050, issued November 25th by the Central Bureau for Astronomical Telegrams at the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts. Itagaki was using an 0.21-meter (8.3-inch) patrol camera, but within 15 minutes he secured a confirming image with an 0.60-meter reflector. The nova lies at right ascension 4h 47.9m, declination –10° 11' (equinox 2000.0).

From the AAVSO site on update to Nova Eri. Also, you can gather more information from CloudyNights at this thread.

At magnitude 8.4 this should be rather easy for most to see and if your into astrophotography it should provide a good object to photo if you have take an image in the area previously or take one now and then several more as it decreases in brightness. Clear Skies.

Edit: Over at AAVSO I made two charts, a large and a smaller. I used the RA and Dec above to plot it. Good hunting.

Update: Here are the actual coordinates: Looks like the progenitor star is listed in the Hubble Guide Star catalog as 5325:1837. Position (2000): RA 04 47 54 Dec -10 10 43
