Shift L3162. Start at 079:13:00 GMT = 08:00am 19 Mar EST End 10:00am 19 Mar SOT Lead DAS (Times will be given in GMT on day 079.) PLAN ---- Continue running load MAR1708A. Finish obsid 8942, an ACIS-S observation of the hot, single, white dwarf KPD 0005+5106 to probe the origin of the 1 keV emission, hypothesized as uiper Belt-like objects hitting the white dwarf surface. Then do obsid 8076, a cycle 8 ACIS-S observation of an early type galaxy in the Virgo cluster as part of a survey to determine duty cycles and distributions of accretion rates on supermassive black holes. Then do obsid 9310, an ACIS-S observation of 3C293 as part of a survey of the z<0.3 3CR sample. Then into perigee passage.

One stored command sequence uplinked, on-board loads good until 083:01:06. A slow ToO was accepted yesterday, will be worked into APR schedule, without requiring any interruptions. MAR3108 products in work. ACE protons and GOES X-rays at background levels. No significant solar activity is expected.
