ACIS Shift Report B7 8:32 pm EST July 29 


HRC relinquished FMT1-->2 at 210:13:10 GMT since they were
unable to carry out their Cal Source measurement due to
too high a pressure.

FP temperature maintaining at from -118.7 to -118.9 C.

We were able to collect Evt. Hist. data (S-array) for about an
additional 1/2 hr in FMT2, and then we put ACIS in thermal standby.

We verified that the ATS (Absolute Time Sequence) for preparing
ACIS for rad. belt passage was executed correctly...it sent the
Stop-Science, Powered Down the Video Boards and did the Dump_Sys_
Config. (ACIS was already safe before the ATS, but at least we
know that the Offline system is working correctly in preparing
ACIS - and HRC - for rad. belt passages.)

We commanded the Event Histogram (I-array) SOP61074 at ~210:23:35
to start collecting data in FMT2 and will continue collecting in
FMT1 while HRC runs overnight. Note that the FP temperature was
elevated (-109.5C) since we had not the opportunity to wait the
~8hrs from Perigee to cool down to -118.9C to commence commanding.
Since we will be in FMT1 we will continue to monitor FP temperatures.
(The elevated temperature Bias map may affect results...)

		(Re-)Planning to be done:

FOR ~Day 212-213:
Rob Cameron is suggessting some (4?) maneuvers during
either the INT_CAL or CC3x3_ICM or RAW_BAIS; in all these cases
we have conflicts during the actual commanding in OBC slots 150 and
151 w/ the proposed maneuver. Mission planning was alerted to this
and will arrange the appropriate ballet of commanding to get us
through this...but we should be wary of ACIS asserting itself
and maneuvering the spacecraft!
