I failed to see USA 129 in the Nordic twilight at 20:32 UT
( and the mystery object 3-4 minutes before, which I  can't find
in alldat.tle below magnitude 14 ! ), but I did see UARS by accident.

What seemed to be SeaStar appeared about 62 sec. early, though
about 2 deg. too high in the east. Checking Molczan.tle, I
found it was #16110, Cosmos 1689, predicted mag. +4.8:
21:03:55.6 UTC Aug.13 at RA 0.866, Decl. +23.95, magn.+4.5
21:04:32.1               RA 2.825, Decl. +38.9
21:05:07.4                  3.51         +48.04

USA 116 #23728 came about 0.3 degrees lower than predicted,
21:10:39.1 UTC Aug.13 at RA 1.893 h, Decl. +19.37 (2000.0)

While still in Aries, it gave a flash of mag.+1, and then
one at +0 about 50 seconds later.

Earlier today, I ran a prediction for the orbit of predicted STS
water dump (in daylight), and found that it probably made a solar
transit at my offica location, 17.89 E, 59.525 N.

PS.  At 04:45 UT Thursday, the SeaStar elset is now 1.6 days old,
and still the latest at OIG
