I derived the following TLE from timed positions reported by Cees Bassa, Russell Eberst and Mike Waterman: USA 245 254 X 1002 km 1 39232U 13043A 13242.89156690 .00021019 00000-0 18320-3 0 09 2 39232 97.8761 306.3459 0533199 186.1661 173.2814 14.79492149 04 Arc 20130830.39-0830.9 WRMS resid 0.048 totl 0.018 xtrk These elements follow the spacecraft's first orbit manoeuvre, which occurred on Aug 30 near the perigee passage of 09:15:27 UTC. I included a synthetic observation at that time, computed from the pre-manoeuvre orbit. I held the inclination and rate of decay fixed at their pre-manoeuvre values. I have updated my table of Electro-Optical KH satellite lifetimes, available in Excel spreadsheet and pdf form: http://satobs.org/seesat_ref/misc/Electro-optical_KeyHole_satellite_lifetime_1.xlsx http://satobs.org/seesat_ref/misc/Electro-optical_KeyHole_satellite_lifetime_1.pdf Ted Molczan _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
