(Curious note about the following H-A predictions for Nagpur; they say "Universal Coordinated Time -5:30 (GMT + 5:30)." Shouldn't they both be "+5:30"? BTW, I know Ulhas has seen these -- just sharing them as FYI for others.) >Search Period Start: 12:00 Sunday, 20 October, 2002 >Search Period End: 01:00 Monday, 21 October, 2002 >Observer's Location: Nagpur ( 21.1500°N, 79.1000°E) >Local Time: Universal Coordinated Time -5:30 (GMT + 5:30) > >PROGRESS M1-9 2.6 18:24:45 49° NE >ISS -0.4 18:25:13 50° NE Here are Quicksat predictions. They have the debris object exactly one minute later than the (to the best of my knowledge) invalid Progress prediction above. 21.142 -79.052 1000.
