Shift L2883. Start at 264:12:00 GMT = 08:00am 13 Jun EDT End 10:00am 13 Jun SOT Lead DAS (Times will be given in GMT on day 264.) PLAN ---- Continue running load JUN1107A. Finish obsid 7838, an ACIS-S observation of NGC 2082 as part of a survey for low level nuclear activity in low mass galaxies. Then obsid 7687, a GTO ACIS-I observation of ABELL 3266 as part of a survey for X-ray outbursts in rich clusters of galaxies. The orbit finishes with obsid 8161, a GTO ACIS-S observation of AX J162246-4946 as part of a program to identify compact ASCA galactic sources. Then perform cti measurements surrounding the perigee passage.

EPH temp: 107.86 degF EPH 27V: 10.37 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day, no issues. JUN1807A products were issued yesterday. However, a fast ToO was approved, and JUN1407A products issued to interrupt the loads starting with the 165:11:40 comm tomorrow. Products will be reviewed by 1pm today, hopefully comments will be emailed earlier. After approval of the JUN1407 load, the JUN1807 load will be reworked for continuity, and to do a "reverse ToO" on HETE J1900 which has had an unexpected state change and no longer meets triggering conditions. An alternate target is being investigated -- the primary issue is that the ToO had been used to pre-cool the EPHIN for the subsequent observation. ASVT has been repaired an is back on-line.
