While on Iridium watch, I saw another satellite going in the same direction at about the same speed. I've watched Iridiums making evening passes approx. 0230-0345 UTC culminating 20-60 degrees at azimuths 80-90 degrees in the eastern sky. Looking for flares but seeing mostly very dim objects even in 8x56 binoculars. They do seem to brighten a little as they reach the approximate azimuth 120-145 and some get just visible to my unaided eye (in an urban area) in the southeast sky just before entering shadow. All of these BTW are going north-to-south. The exception was last night at approx. elev. 10-20 az. 357 a flare was seen through the binoculars but would not have looked like much with the unaided eye. This one culminated at elev. 86 az. 267.4 at 03:49:46 UTC date 22 Sept. 97 UTC (Sept. 21 local) and was Iridium 11 #24842 going north-to-south. Anyway, I was watching through the binoculars Iridium 16 #24841 culminating elev. 31 az. 82.8 at 02:57:25 UTC. I *believe* the dimmer object was Iridium 16 judging from what the others have looked like. I also saw a brighter object about one third binocular field northwest of the Iridium going also north-to-south at about the same speed. Date was 23 Sept. 1997 UTC (22 Sept. local). It was quite a bit brighter than the Iridium. Can anyone identify this unknown? Jake Rees Burbank, Calif., USA (118.3117 W, 34.1817 N)
