Shift L1398. Start at 140:13:00 GMT = 08:00am 20 May EDT End 10:00am 20 May SOT Lead DAS (Times will be given in GMT on day 140.) PLAN ---- Continue running load MAY1903B. Doing obsid 4027, continuing HRC-S/LETG observations to study the AGN outflow seen as an ionized absorber in the bright Seyfert 1 galaxy Mrk 279. Then we will do obsid's 4354 and 4355, ACIS-I calibration observations of G21.5-0.9.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports in the past day. No problems. One load segment uplinked, on-board loads good until 144:13:00. MAY2603A products were distributed this morning for a load review at 2pm today. Need to watch momentum buildup and management during a long series of Fornax A observations during the next two weeks. The IRU-1 current shift on day 138 was noted to have an accompanying bias shift. This was small, ~0.005 deg/hr, which is within spec. There will be ASVT testing today of the eclipse patches. Telecon on rad zone pad time 3PM EDT 405-244-5060 1165#. This review the data from recent radiation zone passages and provide a recommendation for the radiation zone pad to be used in the JUN0203 schedule.
