PLAN
----
Continue running load MAR06B. Continue obsid 12250, an ACIS-I
observation of A853 as part of a volume limited sample of lower mass
systems, to calibrate X-ray mass against mass estimated via the
Sunyaev-Zel'dovich effect. Then do obsid 12822, an ACIS-I observation
of the merging galaxies GZ_merger_AGN_12 to search for binary
AGN. Then do a series of 6 calibration observations of A1795 to
monitor the contamination build-up on ACIS-I. 

NOTES/ISSUES/PROBLEMS
---------------------
At present rates, fluence will be 7.67E8 at next comm, about 2E9 at
RADMON. But rates are decreasing steeply, so we may avoid a
shutdown. A telecon after the standup meeting decided that we would
send normal email this afternoon to call for a 3:30pm EST teleconif
the rates were high enough that there would be any potential for
shutdown prior to next RADMON disable at 70:22:01 (Friday 5:01pm EST).

From the 9am status meeting:
Three supports, no issues. One stored command sequence uplinked,
on-board loads good until 072:17:55.
MAR1411A products have just been released for load review at 3pm
today.
The gyro 2 current 1 has spiked above the 150ma yellow limit during
the night. (Back at 117.6 at present).
The Mar 7 CME has hit, ACE soft protons peaked above 50000(?) at
about 0600. Will need to watch through the day.
There will be a 7th floor power outage Saturday, between
passes. Backup power will be available.
