Russell Eberst reported new observations of the payload: STSS-ATRR 864 X 876 km 1 34903U 09023A 09129.94853581 .00000000 00000-0 00000-0 0 00 2 34903 98.9128 228.1111 0008048 261.3570 98.6686 14.06067333 04 Arc 20090505.9-0509.96 WRMS resid 0.029 totl 0.012 xtrk In order to more fully document the history of the 2nd stage, I have propagated the above elements of the payload back to the first ascending node after launch, then adjusted the epoch and mean anomaly to Russell's two observations of the 2nd stage, as it slightly trailed the payload, about 10 min before the first of its manoeuvres to its present orbit: STSS-ATRR r 864 X 876 km 1 34904U 09023B 09125.89243617 .00000000 00000-0 00000-0 0 04 2 34904 98.9128 224.1202 0008048 272.6993 87.3254 14.06067333 02 Arc 20090505.9-0505.91 WRMS resid 0.055 totl 0.011 xtrk My second pass of the rocket was clouded, so my latest version of the present orbit remains: STSS-ATRR r 230 X 800 km 1 34904U 09023B 09130.12063158 .00471594 00000-0 20692-2 0 07 2 34904 112.6398 228.2610 0413213 299.4753 56.5775 15.16275225 07 Arc 20090508.88-0510.13 WRMS resid 0.054 totl 0.037 xtrk Prediction time uncertainty tonight *should* be well under 1 min, but I have lingering doubts about the eccentricity and the rate of decay, so caution is in order.
