Doing the ACIS "undercover" background observation, then obsid 4713, part of a series of ACIS-S observations of the Sculptor dwarf spheroidal galaxy to study the binary X-ray population and the duty cycle of variability and transients.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 0.7400 mu-a B-leak = 0.1440 mu-a Ascending through 78378 km. ACIS focal plane temperature -119.5 degC. EPH temp 52.13 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports in the past 24 hours. No problems; however there were two data streams during the DSS-24 (Goldstone) pass this morning. We are doing an ACIS undercover background observation. The HRC (corner) is in the focal plane, but we are in format 2. Products for the two week NOV0804 load are out this morning, for a load review today at 4pm on #1165. Other meetings: Today at 10am, action room and #1159, Discussion of EPHIN thermal model and decision on mission planning guidelines. Today at 2pm, Flight director board, Rino will present plans for the upcoming Lunar eclipse. No action is required for Chandra. Tomorrow at 11am, action room and (405) 244-5060 pin # 1159, preliminary briefing on the propellant line cooling issues. FOT is seeing dropouts of the MUPS 2B thermistor. Excursions to -30 deg, recovers, repeats, and recovers. This behaviour has previous been seen on the 2A thermistor.
