Patrick - Reading the Raupe report at http://lunarnetworks.blogspot.com/2009/05/moon-at-lcross-impact.html - a little closer - Raupe's 18:26UT impact time estimate is Raupe's own extrapolation from ephemeris data based on what LCROSS Team leader Colaprette said during the May 21 news conference. I conclude that the Raupe impact time estimate is less reliable than the May 25 LCROSS Team LCROSS Observing Group posting and the LCROSS Facebook posting on May 26 - after the news conference - that put the impact much earlier in the day at 10:30-13:30 UT. As noted above, in the 10:30 to 12:30 UT timeframe - the impact is observable from Utah. - Kurt P.S. - Not sure what you mean by "this list" with respect to: http://lunarnetworks.blogspot.com/2009/06/kaguya-at-perilune.html
