SOT Lead	Ed Kellogg

Plan:  
---- 
OBSID: 01851, RX J0822-4300 2001:025:12:15 HRC-S NONE.
 RADIO-SILENT NEUTRON STARS IN SUPERNOVA REMNANTS.

REAL TIME OBSERVATIONS				GMT	OBSID

Notes from 9 am  meeting
------------------------
OPS: 
	Passes		3 over the last   day(s) 
	Data loss	none
	Load is good -> 029:04:48
	CAPs		690B LETG manual retract
	next passes	1800, 0300, 1200


MP:	Jan 29 load out again for final look by PCAD & ACA.
	Feb 05 load going will. Review expected Monday.
	There was a meeting yesterday on OFLS 9.1 test
plans. Completion of these plans is expected by tomorrow.
SOT MP still needs to look at the newly changed SOE files.

S/C:	 Reno will present the plan for the spring eclipse shortly.

GOT:	GRETA. Several workstations did not get running properly
during the LETG retraction operation. This will be investigated.


SOT:	Radiation continues to gradually decrease.
	LETG manual retract went nominally. There were 7 small moves,
like last time.
	SOT GRETA and ACA workstations, successfully received TLM from
new server.

ASCDS:	No QL processing until the weekend.
