Notes:
-------
(1) Possibly last observation of #90006 as it is now moving into daylight.
(2) Did a search for XSS-11 - negative ( only found Noaa 15 )
(3) Searched for the various new unknowns - no luck. Its obvious that the
observed "discovery arc" is far too small making it almost impossible
to produce a meaningful orbit. I have still to come up with a "simple"
solution.
Cheers
Greg
