PLAN
----
Continue running load FEB1102D. This entire orbit is the ACIS-I obsid
3294, HDF-N deep survey. The HDF-N deep survey will last
the remainder of this week, and upon completion next week we will have
accumulated 2 million seconds on this field.  All HDF-N data is public
domain immediately.

Next Comms:
 046:1430 to 1530
 046:2310 to 0010
 047:0905 to 1005
 047:1520 to 1620
 048:0115 to 0215
 048:1100 to 1300
 048:2135 to 2235

NOTES/ISSUES/PROBLEMS
From the 9am status meeting:
	Three supports, all routine. One load segment uplinked,
onboard commands good through 049:20:27. Products for FEB2502A
expected out today for email review. Monday is a holiday, email
comments due on Tuesday.
	We saw ACE 112-187 keV proton flux rise 3 orders of magnitude,
to ~ 10,000, from Tuesday's CME. They are now falling, to about 1500. 

Quick look data:
