While we're waiting for Those Pictures, here are a couple of shots of LCROSS from our campus observatory last night (0221, 027 UT on 15 July). 4 minute exposures tracking expected motion from the Horizons ephemeris, within 20 degrees of the southern horizon and fighting summertime haze as well as city lights. I wanted to catch it before its inclined orbit takes it too far south, after which it spends a week or so as a predawn object. The range was about 563,000 km, and the Centaur is no bigger than a CSM/LM combination, so this is a more difficult target than spotting an Apollo enroute was. (On the other hand, nobody had CCD imagers in 1969).

Here's a map of the approximate locations of the three polar impacts - LCROSS (counting as one) and MIP and Lunar Prospector. Only approximate as we still don't have actual coordinates for MIP or the LCROSS target.
I have taken the Cabeus area from LOLA data. It's much better shown here than on the current map on the LCROSS website, which appears to show Cabeus with half its real diameter. That older map is derived from an outdated USGS relief drawing. Phil -------------------- ... because the Solar System ain't gonna map itself.
