Hi Tim and Others;

It would be very interesting to learn what object (asteroid or comet) was likely to slam into Jupiter like that. It has to be near the magnitude of the Shoemaker Levy 9 fragments in size to make an earth sized scar like that. I find it alarming that none of the NEA surveys have come up with a possible candidate for it and that we've had 2 such "once in a life time" events in 15 years!

According to Space Weather:

http://spaceweather.com/

the dark impact scar on Jupiter is still visible and there are new images of it posted from all over the globe there too.

So if you haven't seen it yet, you may still be able to.

To find it, the red spot should just be rotating into view from the east and the spot should be centered horizontally but near Jupiter's south pole. I have not seen it yet, but the reports indicate it's pretty obvious, even on your monitor or with an eyepiece.

Lastly, I'll be posting Astro IIDC 4.05 B3 likely tonight or tomorrow, which fixes a potential over oscillation guiding bug that I finally tracked down this week after several testing session to 3:30 am this week. One stupid line of code was commented out for some reason, and I have no idea when I did that or for what reason - but that was what is causing it. The bug has the highest likely hood of happening  as you increase the guide star exposure time too.

TTYL..

Hi Folks;

It's official.

That had to hurt!  ;oD

As I posted on CN today, I wonder if anybody might have been taking deep images of the jupiter vicinity in the last few weeks or months, say looking for faint satellites, and thus might find a pre-impact image of the object?
