(Times will be given in GMT on day 094. In general
times are rough, not precise.)

PLAN
Continue running load APR0200. Finish OBSID 867, ACIS-S observation of
Q1331+170. Do OBSID 900, ACIS-I observation of MKW 3S, followed by 664
ACIS-S observation of 1735-269. We then do a series of calibration
observations of E0102. It is intended that these cal observations be
interrupted tomorrow to do the Cyg X-3 TOO.

Next Contacts:
 095:00:10 to 01:10
 095:09:55 to 10:55
 095:19:00 to 20:50

NOTES/ISSUES/PROBLEMS

Chandra.snapshot has halted, needs to be restarted.

From 9am status meeting:
	9 Successful SSR dumps over the weekend. Commands loaded
on-board good through day 098:06 (But the Cyg X-3 TOO will pre-empt
these on day 95).  
	Review at 1pm today for Cyg X-3 TOO load products. APR0900
load not affected by TOO, 1st load review expected tomorrow.

Meetings: on Wednesday after 9am status, a comparison of new safe mode
recovery features and the changes in the procedures.
	Today at 3pm, a telecon (918 222 7065, 1165#) on updates
to the initial Safe mode response OC procedures (i.e., the activities 
prior to starting safe mode recovery)
	Thursday 2pm, Action room, planning for the test procedures to
be used on the next ONLS/OFLS deliveries.

Quick look data:
OBSID 944, ACIS-I observation of SGR B-2, can't see anything on full image
OBSID 857, ACIS-S observation of B20331+39, looks good.
OBSID 907, ACIS-I observation of QB1429-008, can't see anything on
full image
OBSID 986, ACIS-S observation of A2219, looks good.
