Re: 5919 late geoflare observations

From: Björn Gimle via Seesat-l <seesat-l_at_satobs.org>

The only two classified objects were :

Sicral 2 (my J object):
40614 15 022B 5919 G 20171028212704000 57 15 0241323-054806 39
and my H object is Mercury 1, identified by Mike from one recent obs by
Greg, and a three months old elset :
23223 94 054A 5919 G 20171028212704000 57 15 0301033-054950 39

The two 34780 obs should be reversed in time, but since I used the same
star positions for both start and end of track, the latter should be 30 s
higher in RA:
34780 09 018B 5919 G 20171028212332000 57 15 0343212+003748 39
34780 09 018B 5919 G 20171028212402000 57 15 0344174+003014 39

But a further complication is that Astrometry.net/SAOimage
<https://l.facebook.com/l.php?u=http%3A%2F%2FAstrometry.net%2FSAOimage&h=ATOSieaxq6rYOjBxht3IgoXjOIjB7fkrDxgXue3hCfZUJ7YSWtKVBoYz69kRtpW9PqS-90C7pqwXKTprgFvLU7goKzn_tMY-X902J1CfatOp8_tkKZFrNMXYPHJFTqYYIb5feKJJSYE>
DS9 do not seem to be consistent/accurate in their pick of positions along
the track. Most track coordinates appear to require an addition of 10-20 s
of RA, but I found one star which was 25 s off its true position in the
other direction !?
