Shift L1156. Start at 263:12:00 GMT = 08:00am 20 Sep EDT End 12:00 noon 20 Sep SOT Lead DAS (Times will be given in GMT on day 263.) PLAN ---- Continue running load SEP1602C. Finish obsid 3132, an ACIS-S monitoring observation of the starburst galaxy NGC2146 to search for an intermediate mass black hole. Then obsid 3083, an ACIS-S observation of the intermediate FRI/FRII radio galaxy 3C 401, and obsid 3304, an ACIS-I observation of the unidentified BeppoSAX source H230236.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.6400 mu-a Descending through 117831 km. ACIS focal plane temperature -119.7. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Four supports, no problems. First segment of SEP2302C was uplinked. On-board loads good through 267:23:55. VCDU rollover occurred about 11:41 this morning. OFLS 9.4 is installed and will be used for building SEP3002 loads. Those products will be out (maybe later today) for an email review Monday. EPHIN had a yellow limit temp violation, but it was due to a 1 deg conversion error in C to F scale conversion. However, we are moving toward the hot season and will watch for, and expect, EPHIN heating. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 3318 AX J0844.8+5004 262:07:25 ACIS-S Target not obvious 2935 NGC1313 SA AND SB 262:09:53 HRC-I Looks good. 4371 NGC1600 263:03:18 ACIS-S Looks good. ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
