Shift L589. Start at 61:13:00 GMT = 08:00am 02 Mar EST End 1:00pm 02 Mar SOT Lead DAS (Times will be given in GMT on day 61. In general times are rough, not precise.) PLAN ---- Continue running load FEB2601e. The entire orbit 217 will be GO observations of the Hubble Deep Field with ACIS-I, OBSID 2234. Then the MAR0501 load will start early, at 063:09:57, to accommodate the GRB TOO. Next Comms: 061:15:45 to 17:45 062:01:45 to 03:45 062:06:20 to 08:20 062:13:25 to 14:50 062:21:40 to 23:30 063:08:10 to 10:10 063:14:00 to 15:00 063:23:10 to 00:10 Orbital events: 2001:062:02:00:38.395 217 ORBIT APOGEE 2001:063:09:45:27.201 217 ORBIT PERIGEE 2001:064:17:29:28.632 218 ORBIT APOGEE 2001:066:01:14:57.917 218 ORBIT PERIGEE 2001:067:08:58:01.308 219 ORBIT APOGEE 2001:068:16:43:00.267 219 ORBIT PERIGEE EVENTS ------ Status at LOS, 061:08:59, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 189.202 deg Dec = 62.239 deg ROLL = 142.003 deg Format = 2 OBSID = 2234 HDF-N SIM FA = -535 SIM TSC = 90567 (ACIS-I) HETG = OUT (79.84 deg) LETG = OUT (78.34 deg) HRC-S HV is ON EPHIN Geom = LARG E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.0 LT 300.

Ascending through 134233 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS From the 9am status meeting: 3 supports, data dumps are current. A 5 hr contact was used to successfully conduct the dark current measurement. As reported yesterday, the ACA monitor window test was successful. Preliminary histogram of numbers of pixels vs dark current shows a rate of warm/hot pixel increase from last Sep measurement which looks smaller than the increase from Aug 99 to Sep 00. The MAR0501c loads have been approved and signed, will start uplinking at the 15:45 GMT contact this morning. MAR1201 planning is in work, encountering visibility problems. Testing of OFLS 9.1 succeeded in giving a pretty good 2 week schedule. There will be a CAP review Monday morning for the patch to be uploaded for next week's short earth eclipse, the last eclipse of the current season. A MAJOR MILESTONE is reached today with the completion of reprocessing! The last OBSID, 915, is running as we speak. Congratulations to the processing team, and the CXC Data Systems Division. Quick look data: No new quick look data. Problem processing obsid 2091 due to an aspect issue, thought to be a fid light. We tracked 3 fid lights as late as 060:07:05.
