Shift L3920. Start at 105:12:00 GMT = 08:00am 15 Apr EDT End 10:00am 15 Apr SOT Lead DAS (Times will be given in GMT on day 105.) PLAN ---- Continue running load APR1110B.Go through perigee passage, then measure acending cti. Then do obsid 11514, an ACIS-S ToO observation of M87 contiguous with the TeV high state, to try to define the location of the TeV gamma rays.Then do obsid 12141, continuation of the ACIS-S observation of the high redshift cluster of galaxies EN1-349, to measure the core gas density and investigate the AGN population of the field. Then five HRC calibration observations of Vega to monitor the optical/UV transmission of the HRC filters. Then do obsid 11341, an ACIS-S observation of PGC085239 as part of a survey of spheroid galaxies to study the effects of environment on accretion activity. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Four supports over the past day. No issues. One stored command sequence uplinked, on-board loads are good until 109:00:06. The pre-approved ephemeris update CAP 648DS was run. APR1910 products are released for a load review at 1pm this afternoon on 111159# HVAC and water will be off this Saturday. Electricity will remain on.
