NOTES/ISSUES/PROBLEMS
The chandra1.snapshot, at
http://cxc.harvard.edu/mta_days/MIRROR/Snap/snap.cgi, shows data from
the pass ending 00:30. The chandra2.snapshot, chandra.snapshot both
are current with the pass ending 10:00, see
http://pegreta.harvard.edu/cgi-bin/snapshot.pl. 

From the 9am status meeting:
	All downlink data current. On-board command loads good through
236:00:18. We had a VCDU rollover at 230:09:54. Last Friday ran CAP
740 for HRC recovery from the SCS 107 trip (reset of door
position) and CAP 675 to enable SCS 107. 
	2 eclipses have occurred, seem nominal, closer examination of
the data to follow.
	Mission planning expects products out this morning for the
AUG2701 load. email review today, load review tomorrow.
	Safe mode recovery simulation was held last Friday. Debrief
today at 10:15am. Darell will compile report and action items.

Quick look data:
No data available, due to lack of obspar's.
