NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
	3 supports, 3 dumps. 1 load segment uplinked, loads on board
good through 071:18:42.
	System database backup is in progress. Should finish this
morning.
	Workarounds/solutions exist for all problems found in MAR1200
load review yesterday. New products are out for a load review
today. Previously scheduled for 1:30pm, will try to reschedule for
2pm. New OFLS 8.0 problem was uncovered, error in position for targets
with both an offset and a roll. Cause currently unknown.
	Next eclipse will be around 069:07 tomorrow morning.
	Testing the revised SCS 105 patch today. ASVT problems postponed
testing from yesterday. 

Quick Look data:
OBSID 335, ACIS-S/HETG observation of NGC 4151, looks good.
OBSID 705, ACIS-S/HETG observation of Cen X-3, looks good.
OBSID 506, ACIS-S observation of RX J1347-114, looks good.
OBSID 964, HRC observation of the Lockman Hole, looks good.
