Yesterday I got two images of IGS 9, 1.9/2.4 s early wrt. 8.9 day old
elset, less than an arc minute below track  prediction.
40381 15 004A   5919 F 20160329191036800 57 25 1443591+281874 55 S
40381 15 004A   5919 F 20160329191020800 57 25 1422135+233064 55 S

No big deal, since the drag term is 0 - in fact it was just 10s off 181 day
old elset.
Which proves it is effectively maintained near the intended mean motion.

Today I have two images of USA 186, not reduced yet, but apparantly 8 s
late on 5.8 day old TLE.
