Shift L522. 
	Start at 360:18:00  GMT

	This is a remote snapshot report. There is no planned on-site SOT 
coverage during Dec 23 -- Jan 1, inclusive.
   
SOT Lead	DAS

(Times will be given in GMT on day 360. In general
times are rough, not precise.)

PLAN
----
Continue running load DEC2500c. Perform CTI after exiting belts, and do 
an ACIS-S/HETG observation of Zw3146, OBSID 1651, for the entire orbit.
