Shift L2841. Start at 122:12:00 GMT = 08:00am 02 May EDT End 10:00am 02 May SOT Lead DAS (Times will be given in GMT on day 122.) PLAN ---- Continue running load APR30B. Currently in perigee passage. Upon egress do obsid 7577, an ACIS-S GTO observation of the millisecond pulsar PSR B1257+12 to test for circumpulsar matter associated with the planetary system. Then do obsid 7427, an ACIS-S observation of the late-M dwarf LSR1835+32 coordinated with optical and radio observations.

DSS-54 experienced a loss of command and telemetry due to an unknown cause, but it returned and all operations were completed. MAY0707B loads were released yesterday, for an email review by 2pm today. The pre-approved CAP for the monthly EIA self-test will be executed today, with tomorrow as a backup. ACE solar protons remain near background, and the sun remains quiet.
