Shift L1477. Start at 219:12:00 GMT = 08:00am 07 Aug EDT End 10:00am 07 Aug SOT Lead DAS (Times will be given in GMT on day 219.) PLAN ---- Continue running load AUG0203A. Emerge from perigee and perform ACIS CTI measurement. Then do obsid 3932, an ACIS-S observation to study the ultraluminous X-ray sources in the spiral galaxy M51. No Comm this shift.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports, no issues. One load segment uplinked, on-board loads good until 222:11:32. Review of AUG0311A had a problem since the TOO pushed another observation (3935) outside its time window. Contact with the observer said the scheduling was permissible. The TOO observer changed observational setup, so a new ACIS parameter block was built for the AUG0311B run. Products expected this morning for an email review today. Safemode recovery simulation will be postponed again. There is a problem commanding the ASVT from Cambridge. NGST/west is trouble shooting -- suspect a TCTS hardware problem.
