(Times will be given in GMT on day 333. In general
times are rough, not precise.)

PLAN
Run load NOV2899e. Observing OBSID 77, HRC-S/LETG of CAL-83.
At 21:38 we start CTI measurements prior to rad belt passage.

Scheduled Comms:
	333:14:00 to 16:00
	333:22:00 to 00:00
	334:05:00 to 05:45
	334:13:35 to 14:45

NOTES/ISSUES/PROBLEMS
Star in slot 4 keeps dropping out of track.  It is a bright
star, I suspect it violates the upper brightness limit. This
is a BAD feature of the OFLS/onboard software system -- a star
at the correct position should be tracked unless it is so
bright that it saturates the ACA pixels! Tracks up to 51400
total counts, magnitude expected was 9.2 with a bright limit
of 6.938. 51400 counts is about 6.88 mag.

Notes from 9am status meeting:
	FEP 0 patch was run, but there were no occurences of
errors, therefore no information.
	16 supports over the weekend, 19 SSR dumps, 5 bad were
repeated, so all data was recovered.
	SOHO is having problems, will use extra DSN 34m times, we
will systematically get switched to 26meter use.
	DSops reports that processing is being held up due to 
lack of definitive ephemeris files.  FOT is about 4 weeks behind,
will give it some attention. Jupiter observations with HRC/LETG
are processed. Jupiter observations of ACIS are having problems 
with Level 0 telemetry decomm..
	 Jupiter HRC/LETG OBSIDs 961, and about 90 minutes of 1464,
were lost due to SCS #93 being disabled following the inadvertent
RADMON trip on Nov 26. This problem was found and corrected in real
time, thus saving OBSID 1465 and most of 1464. 
	FOT MPS is building products for DEC0599 load, products
expected late Tuesday.  OR list for DEC1299 is needed.
	Marv will call a meeting for 2pm Tuesday to plan the test groups
for ofls 8.0.
