I derived the following using my observations of 2001 Aug 04 - 05 UTC: USA 129 15.0 3.0 0.0 5.1 v 1 24680U 96072A 01217.13679977 .00025763 00000-0 35000-3 0 01 2 24680 97.9284 278.5951 0512000 71.4764 294.1452 14.75970433 05 Only the RAAN, argument of perigee, mean anomaly and mean motion were included in the differential correction. Mean residuals are about 0.02 deg. These elements should be accurate to within several seconds in time for tomorrow's passes. The manoeuvre turns out to have been larger than I had believed. It occurred at the perigee passage of 2001 Aug 03 at about 15:48:33 UTC. I obtained the following points, all of which are appulses, observed in poor conditions: 24680 96 072A 9999 P 20010805015051750 17 25 2306333+253800 38 S 24680 96 072A 2701 P 20010805032807360 17 25 1317417+093700 38 S 24680 96 072A 2701 P 20010805032837960 17 25 1246000+162800 38 S The sky was fairly clear, but Point 1 was observed using hand-held 7x50s, near a badly light-polluted street corner, several kilometres from my usual site. Points 2 and 3 were observed below 10 deg elevation. Point 1 was roughly 0.2 deg above 56 Pegasi. Point 2 was roughly 0.2 deg above 59 Virgo. This appears to be the least accurate of the three points. Point 3 was roughly 0.2 deg below 27 Coma Berenices. Site 9999: 43.657 N, 79.385 W, 100 m (a one-time use location) Site 2701: 43.68764 N, 79.39243 W, 230 m Ted Molczan ----------------------------------------------------------------- Unsubscribe from SeeSat-L by sending a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@lists.satellite.eu.org http://www2.satellite.eu.org/seesat/seesatindex.html
