no pass

Notes from 9 am  meeting
------------------------
OPS: 
	Passes		7 over the last  3  days
	SSR dumps 	83
	Data loss 	none  
	Load is good -> 262:23:00
	CAPs		562 on Friday, squeegee #10
			650 Saturday, short eclipse OBC software patch
	next passes	1700, 0030

MP:	We may have a load review today for SEP2400

S/C:	We had high proton rates over the weekend, but no
	shutdown. The last earth eclips of the series is today.

GOT:	-

SOT:	Radiation dropping. 

ASCDS:	Two OBSIDS gave trouble - #648 and #008. Both had unusual
events in the data. For example #008 had a reacquisition. The ASCDS
requests that they please be notified in advance of this type of
situation so they can better employ special processing.
