Way to go Jerry! Very impressive. I remember well when you were still imaging on film with your 10-inch. Technology has sure come a long way, no? Kim

The amount of ejecta is incredible!!! And the pictures returned by the impactor on the way in will make a great movie. Several of us have noticed a definate brightening of the comet but only by maybe one magniturde. When the impact was announced the crowd here at SPOC erupted into yells and applause. :-) Patrick ___________________________________ NOCC, http://nocc.sourceforge.net

The Grim scope (and several portable scopes ) are all set up and ready here at SPOC. NASA TV's coverage of the "Wallop" is about to start. So I guess we're all ready to go. Let's hope we all get to see something spectacular. Go Deep Impact! Patrick ___________________________________ NOCC, http://nocc.sourceforge.net

Deep Impact
by Lockman 04 Jul '05

04 Jul '05

I've been trying to find out what other observers from the ground may have seen last night when Deep Impact took place. We took the telescope an Odyssey 8 out to watch. Seeing and darkness were excellent. Using coordinates I got from "Cartes du Ciel" software of RA 13:38:09 Dec -09:33:13 and plotting this point in the Uranometria 2000, I star hopped to it from Spica. I'm not even sure the coordinates were correct. There was a very faint < 9.5 magnitude (by my estimation) object not shown in the Uranometria at this spot. It was the sort of thing that needed averted vision even through the telescope to see. I wasn't sure if it was the comet or if it was just a star fainter than the Uranometria plots. Shortly after the impact time, either my eyes adjusted so I could see it better or it actually brightened to around 9.5 or maybe even 9.0. I no longer needed averted vision to see it, but that was about it. I'd be interested to hear what others may have observed.

First European Impact Images
by John Peterson 04 Jul '05

04 Jul '05

When looking at the first European impact images from Patrick's link I noticed how much more exposed the post-impact shot was (all of the stars are much brighter). Did the ESA people do this to exagerate the effects of impact? I would like to see equally exposed before- and after-images to make a more valid comparison. http://www.esa.int/esaCP/SEMERX5DIAE_index_0.html John R. Peterson

Tempel 1 info

I've been looking for a few factoids that may have been published, but I just haven't come across yet: 1. Size and mass of Tempel 1? 2. Tempel 1's velocity through space? 3. Distance from Earth at time of impact? 4. Position (celestial coordinates) of Tempel 1 at time of impact? Kim

52 minutes to impact. We've got the comet in the Big Scope but despite all of that aperature the comet is very faint (maybe it's all the smoke in the sky). Mission control says they may not have confirmation of impact or pictures until 30 minutes past impact. Patrick ___________________________________ NOCC, http://nocc.sourceforge.net

Deep Impact
by Chuck Hards 03 Jul '05

03 Jul '05

Has anyone seen an image from the Impactor posted yet? Nothing new on the ESA page as of this posting... 7-1/2 hours to "Wallop Time"! I don't know about the rest of you, but this mission stirs a deeply juvenile curiosity in me. It's prodding the same parts of my brain that, 40 years ago, would have been responsible for giving me an impulse to throw a stone at a hornet's nest.
