Shift L2458. Start at 104:13:00 GMT = 08:00am 14 Apr EDT End 10:00am 14 Apr SOT Lead DAS (Times will be given in GMT on day 104.) PLAN ---- Continue running load APR1006B. Perform ACIS cti measurements while emerging from perigee passage. Then do obsid 6846, an ACIS-S observation of the interacting galaxies AM 0630-353. Then do 6873, an ACIS-S observation as part of a monitoring series of the Seyfert type 1.8 galaxy NGC 1365, to study transitions from Compton-thick to Compton-thin states.

EPH temp: 87.33 degF EPH 27V: 23.30 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Two supports, no issues. The CAPs 750 D and E to dump OBC memory were unsuccessful. There were intermittent dropouts and GRETA capture issues. Thought to be a GRETA problem. The SGIs may have all the data correctly and we may be able to recover the dumps from playback data in hand. Meanwhile we are investigating the problem.
