The initial report was from Riverside, CA,\nUSA, 34.0 N 117.4 W, Elevation 250 meters.\n\n\nAfter much checking, I believe what was actually seen\nwas an upper stage of Soyuz booster that launched\nCOSMOS 1184 on June 4, 1980.\n\nIn the original post, the observer reported the object\n\"directly overhead\" at 6:10pm PST (0210 UTC \n06 November 2008). The SL-3 rocket body \nwas 80 degs high at 6:10:39pm PST.\n\nAO-51 on the other hand was 83 degs high a\nminute and a half later at 6:12pm PST, so the timing\nis a better fit for the SL-3 R/B. The SL-3 R/B is\nabout 12 ft. long and 8 ft. in diameter. It orbits\nabout 140 miles lower than AO-51.\n\nIn the summer of 2006, I made a visual sighting of \nAO-7 using a 70mm \"goto\" telescope at 25 powers\nof magnification It took many tries, but finally on a\nnear perfect 88 deg pass I spotted it. It was about\n7th magnitude at is brightest and very tiny.\n\nSince then I have made a couple of serious attempts\nto spot AO-51 using 11x80 binoculars, and a 70mm\ntelescope and have not succeeded. My next attempt\nwill be with my 8 inch telescope, but not until the\nweather gets warmer.\n\n>From my personal experience, I do not think AO-51\nwould be visible to a casual observer. One must also\nkeep in mind AO-51 is in a polar sun synchronous orbit.\nThis is a very popular orbit for satellites to be launched\ninto and consequently there is a lot of stuff up there.\n\nIt's kind of like watching US-101 during the rush hour\nand expecting to see a white car at 4:30 PM. \nYou'll see one.\n\nEnter the lat/long for Riverside, CA, \n( 34.0 N 117.4 W, Elevation 250 meters), plug in the\nfollow keps, set your clock to 0200UTC, 06 NOV 2008,\nand see what you think....\n\nSL-3 R/B\n1 11822U 80044B 08311.47990140 .00000945 00000-0 44143-4 0 1751\n2 11822 081.2402 315.5175 0023019 261.6853 098.1731 15.18617526552470\nAMSAT ECHO\n\n1 28375U 04025K 08311.64072703 .00000014 00000-0 16651-4 0 2382\n\n2 28375 098.0621 328.1455 0085038 080.2834 280.7950 14.40623296228910\n\n\n\n73, Armando, N8IGJ\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n", "attachments": [] }
