Notes:
------
(1) Since the orbital period of #90027 was somewhat uncertain and I had
not managed to see it on the current elements, I decided to do an
orbit plane scan and found it with no trouble running considerably
late. This observation should manage to tie the period down and I
expect to see the satellite tonight running on new elements I made-
provided clear of course.
(2) The other satellite passed through the field of view during the
expected "window" and was initially unknown but subsequently
identified.
(3) I have still to go through the DVD recording made to identify the
other satellites seen during the plane scan.
Cheers
Greg
