SOT Lead	NONE (das at CXC staff meeting)

(Times will be given in GMT on day 67. In general
times are rough, not precise.)

PLAN
Continue running load MAR0500d. Finish CTI measurements, Do OBSID
348, ACIS-S on NGC 4151, followed by ACIS-S observations of 
SN1998s (OBSID 768), NGC 4258 (OBSID 349), and the Crab Nebula (OBSID
769). Next is an HRC-S/LETG calibration observation of Capella, (OBSID
58), until 068:16:44.

Next Contacts:
        067:13:30 to 15:30
        068:00:40 to 02:40
        068:10:30 to 12:15
        068:10:30 to 12:00
        068:19:25 to 20:50

NOTES/ISSUES/PROBLEMS
From 9am status meeting:
	3 supports, 3 dumps. Ran CAP 468 to dump the eps memory locations.
We went through eclipse #5 of the current season, everything nominal.

Products for the MAR1200 load were out yesterday, review at 2pm
today. This is the first review conducted under OFLS 8.0. Kevin is
working on the MAR1900 load.

Cambridge Ops had planned the monthly data base backup at 11am today,
but it will be postponed until tomorrow because of the on-going
Mar0500 work.

Level II board yesterday approved the change of P4GM ephin threshold
K-constant. This allows proceeding with the change to shorten the
radiation belt pad times to 10 Ksec. Change to SCS 105 was discussed,
and some further work defined to null out the commmands at the end.
