Notes from 9 am  meeting
------------------------
OPS: 
	Passes		2 over the last  day 
	SSR dumps	-
	Data loss	none
	Load is good -> 007:02:00
	CAPs		none
	next passes	1445,0000


MP:	Another load review this pm. Ten starcats to replace. 
	The next week's load has an LETG observation.  The LETG
insertion and retraction comm times are 010.11:20 - 010.13:20 and
012.15:30 - 012.16:45.
	
S/C:	OK

GOT:	OK

SOT:	Radiation is low and steady.

ASCDS:	Having a problem with day 363 data. This may be related to
data losses seen by the FOT on that day. It is being investigated.
