NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
	3, 34 meter supports in last 24 hours, all successful. Last
segment of MAR1901c load to be uplinked next comm.
	VCDU rollover will occur at 081:03:21.
	Load review yesterday, revised MAR2601b products are out, load
review today at 2pm. 
	A FOT/TRW telecon was held yesterday on the OBSID bit flip
problem. Four possible causes are being pursued, no one cause seems
particularly likely.
	The OTG SOP's will be checked out on ASVT tomorrow, starting 11am.
	Preparations being made to quickly process the TOO/DDT data on
GRS 1758-258 when it arrives next weekend.

	Meetings:
	10am Star Selection Working Group. review of parameters in 
	  Characteristics and Constraints files and in namelists
	  405 244 5060 1165#
	3pm OTG working group.
