Seems that Anthony Wesley has recorded another impact on Jupiter. You can find it discussed in this blog and at this forum/thread at IceinSpace where Anthony goes by the name of bird. You can see the movie here .
An early hypothesis that I would put forward is that Anthony seems to focus on Jupiter a lot and because of that, he is able to capture strikes on Jupiter. I think what is very important is that Anthony is confirming something most astronomers know, that Jupiter is the vacuum cleaner of solar system. No matter what, it is great work by Anthony and shows how an amateur can have such a major impact on professional astronomy.
Clouds here so still no observing.
