I imagine it could be difficult timing shadow down to the second on a slow satellite. However, since the times are quite consistent, and SkyMap does a good job of predicting shadow, I predicted shadow tracks for all geos. There are very few at the required position. On Oct.2, GE-2 97002A #24713 should disappear 4:59:32 and reappear 5:59:51, mid=5:40.5 - 10.8 The XM-1 (Roll, #26761 01018A) satellite (see design in link provided by Kevin recently) is close, 5:41.1. Brazilsat B3 is 3 minutes earlier, and there seems to be larger gaps to other satellites. For a quicker and safer ID, time its appulse to a bright or otherwise identifiable star, such as the mag +6.1 HP#177420 near RA 23:48, dec.-6.3 around 04:47 UTC.
