The elements used should be after Progress docked. I don't know
the time, but took epochs 198.84, 199.41, 200.17 and fitted ndot2
(using SatAna) with 0.2 sec. residuals.
The SGP predictions result in culmination around 10:26 UT Aug.11.
-------------
10.8 cm flux = 150.000000
Residuals for final evolution:
99198.842893 2
99199.160523 -218
99199.414622 0
99199.859296 -22
