Shift L3904. Start at 089:12:00 GMT = 08:00am 30 Mar EDT End 10:00am 30 Mar SOT Lead DAS (Times will be given in GMT on day 089.) PLAN ---- Continue running load MAR2910A. We have finished obsid 11176, a ToO ACIS-S observation of a nearby gamma ray burst, in a multiwavelength attempt to determine the energetics of the associated supernova explosion. Then go through perigee, measuring ACIS calibration source on ingress and egress. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Two supports over the past day. DSS-65 had a bad connection on the Antenna Pointing Controller and could not support Chandra. The SSR rolled over to side B. Next Support with DSS-27 was started earlier and extended, and the SSR roll-over data was recovered. Operation is back on SSR-A. One stored command segment was uplinked, on-board loads good until 093:15:40. APR0510A products are expected out this afternoon, for a load review at 2pm tomorrow. CAP review of 1148B, a contingency to stop the momentum dump during the third high temperature MUPS firing test Thursday night EDT, will be held at 9:30 EDT this morning.
