Shift L2454. Start at 100:13:00 GMT = 08:00am 10 Apr EDT End 10:00am 10 Apr SOT Lead DAS (Times will be given in GMT on day 100.) PLAN ---- Continue running load Apr1006B. Continue obsid 6974, an ACIS-I observation of Abell 2717 to study the dependence of gas fraction on cluster mass. Then obsid 6890, an ACIS-S observation of SDSS J220445.36+0031 to study outflows in bright, absorption line quasars from the SDSS survey; obsid 7252, an ACIS-S observation of NGC 7060 to study the hot gas in an edge-on spiral galaxy; and obsid 6639, and ACIS-I observation of SAG A* to monitor X-ray transients in the galactic center.

EPH temp: 91.63 degF EPH 27V: 19.52 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Nine supports over the weekend. Two issues: DSS-46 lost telemetry for about 2 minutes for an unknown cause, recovered by manually retuning telemetry receiver; and DSS-54 had randowm dropouts due to a malfunction with a T-1 line, recovered by pulling offending line. Two command load segments were uplinked: on-board loads good until 104:12:00. APR1706 products not out until tomorrow; FOT will use today's new Post-Final OR list which replaces a target scheduled in the APR1006 week, and updates parameters for the RS Oph DDT observation. Meetings: Six Sigma briefing today at 1pm. 1165# Look ahead: An upcoming spacecraft anomaly training simulation is planned for April 25, start time 8am EDT.
