If this was the position the HST was pointing at on 3-JUL-05, 2:35:30 UTC then specular reflections from the "aft shroud" (as I now learned from Ed Cannon that the bottom of the HST is called) would have missed the Earth all together and it might have been the side or the lens cap instead. The HST timeline site http://www.stsci.edu/observing/weekly_timeline.html which Ed Cannon mentioned in his reply didn't seem to cover that particular time and it mentions projects rather than sky coordinates. Still, every now and then a known object is given as a target and on those occasions it would be useful for flare predictions. Actually, I just checked pointing at Tempel 1 again. Anyone on Big Island Hawaii: If HST is pointing at the Comet on 5-JUL-05, 5:38:30 UTC you might see an aft shroud flare. (More northerly latitudes don't seem to get these "Comet pointing flares" for the moment.
