To be fair, given the bright background and having looked at the raw data, that Hubble image looks like a bad scan of an already poorly processed version. Looking at the moons in some of these early HST images and comparing them to modern webcams, the HST images have a slight edge, but that is all.

Yep, that's got "scan" written all over it, down to the print scratches on the high res version.

1) It would probably be harder to spot by an amateur and thus more likely to be missed

I'm sure that's true, but the fact that we're just two weeks from the 76th anniversary of film comedian Will Hay doing just that shouldn't go unremarked

The HST observations have begun...the first set wrapped up about four hours ago.

Is that a restricted-access page, Ted? I get nothing but the frame.

Surprisingly good news, in any case!

It did that for me on the first few tries.

BTW, Gemini has also looked http://www.gemini.edu/node/11300

I'm assuming that with Hubble still in it's recommissioning phase and images not supposed to be released until some time in September we are unlikely to see these observations for some time??

EDIT: OK just saw this at spaceflight now http://www.spaceflightnow.com/news/n0907/24hubble/

"Engineers programmed Hubble to spend a few hours observing Jupiter Thursday afternoon. Imagery of Jupiter could be released by late Friday, according to Ray Villard, spokesperson for the Space Telescope Science Institute."

Definitely looking forward to this first example of the improved capabilities with WFP3.

Yes, and it's a shame they couldn't get the High Resolution Camera on ACS working again.

They repaired the ACS HRC, but it is much more complex to operate and would take much more time. At any rate, the WFC3, while having a much larger field of view than WFPC2, has significantly higher resolution than the PC chip in WFPC2, so this should be good.

They repaired ACS HRC? When? Last I heard the last servicing mission wasn't able to do that. Were they able to do it from the ground via some software method?

OK, I see that now, I didn't realize the HRC had further problems (although they are still trying to find a work-around).

Good SpaceflightNow article re yesterday's Hubble obs; images may be released later today!

YESSSSS!!! smile.gif

Wow. Obviously these are rush images that haven't been calibrated, but at first blush that hit looks a lot more pronounced than I remember for even the largest SL9 fragments. In fact, it almost looks like more dark material may have been boiling out from the deeper levels of the atmosphere since the impact occurred, and the 'ejecta field' to the left of center's still there.

Wow. Just wow. WFC3's performance is looking pretty good at this early stage as well!
