I should have been more active, but forgot to check the progress of MM,
and the overdue(?) correction - see
http://www2.satellite.eu.org/seesat/Jul-1999/0076.html

I observed USA 116 on Sep.4 at 22:36:59.6, 22:37:29.1, 22:38:09.1 UT
right after shadow exit, but I was using a new voice-activated tape
recorder instead of pen-and-paper. I seem to have moved the volume
control, so it never started, after the initial tests :-(>

The first position probably was RA 10.68 h, dec.+53.7 (2000)

I tried from town on Sep.8, but I only waited 3 min after prediction.
Anyway, my binocular limit was about 5.5 due to haze and city lights.

Since 14.83 is near the usual max.MM, and since BOTH satellites 
maneuvred, it was probably a large reboost of about 0.10, so it
must have occurred unly a few hours earlier, and the satellites
will be delayed by another 10 min./day.
