PLAN
----
Continue running load FEB2105B. Do obsid 6229, a piece of the long
ACIS-I image of Cyg A to study interaction of the jets with the
cluster medium. Then do obsid 5519, an ACIS-S observation of the
nearby, radio-bright pulsar B1133+16; obsid 5604, an ACIS-S GTO
observation of the gravitationally lensed, high redshift quasar
SDSSJ0924+0219. 

Next Comms:
054:1850 to 1950
055:0300 to 0500
055:1100 to 1200
055:1825 to 1925

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
Three supports over the past day.  No issues. One load segment
uplinked, on-board loads good until 057:18:42.
FEB2805 products still in work, load review expected tomorrow. MAR0705
work is starting.
Good tagup with SOHO engineers yesterday, to discuss common EPHIN and
propellant line freezing issues.  No experience to directly help with
the Chandra concerns, but they have some relevant performance data.
UPS system is disconnected Feb 22-24 during 9am-4pm hours to install
battery monitoring software, recommended following last summer's UPS
problems. 
ACIS operations/IPI team monthly meeting today, NE-80 6th floor, 4pm. 

Quick look data:

5928  M31*		 052:16:38  HRC-I NONE	     looks okay. there
				         is a streak just to the W of
					 center which looks strange.

6249  B1152+199		 053:06:22  ACIS-S NONE	      Looks okay.
