Derek Breit, Tim Luton, Mike McCants, Steve Newcomb, Jim Nix, Alberto Rango, Greg Roberts, Peter Wakelin, Brad Young, and I, contributed observations used to determine one or more of the following element sets. I was able to fit a reasonable orbit to the last 10 days of observations, but the time residuals on May 27 are a bit high, which may indicate a small manoeuvre around that date.

Mike McCants provided several search elements, which enabled Greg to make the confirming observations last night. I used a fixed estimate of the eccentricity in deriving the following elements. Allowed to vary, the eccentricity resulted in a perigee height aroung 250 km, but I think it best to wait for additional observations before accepting that. 06675A 312 X 35613 km 1 90059U 06675A 10149.79778415 .00000246 00000-0 19891-3 0 06 2 90059 28.0545 140.7924 7251588 259.2149 19.0285 2.28674532 08 Arc 20100527.97-0529.88 WRMS resid 0.005 totl 0.005 xtrk Ted Molczan _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
