Notes from 9 am  meeting
------------------------
OPS: 
	Passes		2 over the last    day
	SSR dumps 	2 , of which 0 failed
	Data loss 	  none  
	Load is good -> day 234:08:20
	no CAPs
	next passes	2335, 0835

MP:	2nd review of load was held. There was one star edit. The
revised products are out and review is being held by email. 
	There is a TOO request pending from last Monday night, with a
one week window. This target was observed serendipitously last
Tuesday. The results are being examined to decide whether to proceed
with the TOO.
	Scheduling for the eclipse stalled in OFLS because of a glitch
in the ephemeris file, giving two ecplipses separated by ~ 1
min. There is a hand workaround.
	The OFLS problem Ken Gage was experiencing is corrected in
OFLS R9.0 orbit event generation, which is awaiting operational
installation(Larry Felton).

S/C:	SCS 82 was approved by FDB and is ready for implementation. 
	Darrell and Bill Davis have noticed a 0.2 ns glitch in the
onboard clock. This is within spec, so not an anomaly. Rino mentioned
that there were recent temperature dips that might be related.
	The new CSDs for the grating were also approved yesterday by FDB.

GOT:	-

SOT: Radiation is low.

OCC Mgr: ACIS meeting yesterday resulted in a plan for CXC to make a
recommendation on squeegee mode implementation to SWG on
Sept. 14th.

Evaluation of QL data
---------------------
The following OBSIDs should be available for review. No comment after
the entry means the QL image has not been distributed yet to SOT.
