My apologies, please remove my previous message with this subject,
since I forgot to paste the elset !

Here is all :

The elements published by Russell Eberst to seesat-l, and in the Molczan
file, agree quite well with recent observations.

The satellite was about a minute late, and slightly higher than the
delay indicated.

The reason I didn't compute a new elset is that it is usually maneuvred
two-three times per year, with a decrease of MM by 0.016 - 0.1 / day each
time. This winter, it has not maneuvred since about 94235, and its MM is
higher than any previous elset I have, so it could maneuvre any day.

If the following elset is used, it should give reasonable positions
until the maneuvre takes place.

USA 86 KH11-9   15.0  3.0  0.0  4.6 92-83A
1 22251U 92 83A   95112.2746703   .00017000  00000-0  20000-3 0    10
2 22251  97.9145 225.7320 0518703 189.2259 169.5391 14.8251917     10

When that happens, the satellite may be delayed by ten minutes per day,
so it will be difficult to recover it, if not checked daily, and any
delayed appearance reported immediately. No precision required for
initial maneuvre report !

PS. At one pass low in the east, I saw three flashes to mag. +2,
about a minute apart.
