SOT Lead	Ed Kellogg

Plan:  
---- 

OBSID: 02310, 821+643 2001:021:09:23, ACIS-S LETG - FINDING THE BARYONS IN THE LOW REDSHIFT UNIVERSE. 
then CAL-ER 2001:023:09:17


REAL TIME OBSERVATIONS				GMT	OBSID

AOS, 3 fids, 5 stars				1600	2310

Notes from 9 am  meeting
------------------------
OPS: 
	Passes		8 over the last 3 day(s) 
	Data loss	none
	Load is good -> 026:09:03
	CAPs		none
	next passes	1600, 0015


MP:	load review for JAN2901 load today at 2:00 PM.
	
S/C:	The CM machine is down, requiring a struggle to get documents
on the Web. A workaround is in progress.

GOT:	A backup machine for freefot1, called chocodile is to be
installed on the SQUIRT system to feed EGSE.

SOT:	Radiation is moderate and generally rising.

ASCDS: after the meeting, a partial was received on the current long
observation.

OBSID   Target		SI         SOT Eval. 
-----   ------		------     -------
2310	H1821+643	ACIS-S/LETG	OK, a source is seen nicely
centered on the ACIS field. The dispersed spectrum is seen as well.

NOTES/ISSUES/PROBLEMS
--------------------- 
ACE 2 hr fluence is 1.6e7 vs. threshold 3.6e8.
