Ah, else where I learned that the object that struck Jupiter was to small to be imaged from earth.

How do amateur astronomers learn?

Milton, recent to the owner/operator observatory experience, I have added a camera recorder that captures 30 frames per minute video from my low light cameras on my scopes.  For the past two weeks I have been routinely used Jupiter as a first reference each night I have set up for a night of observing, which means I have 10 or 15 10 to 20 minute videos of Jupiter at or near magnitude 11.  If the object is that bright, I may well be able to see it in one of my wide field cameras.


You can see my recording system, and some video clips at:

Wish me luck.

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..
