Shift L1616. Start at 358:13:00 GMT = 08:00am 24 Dec EST End 12:00 noon 24 Dec SOT Lead DAS (Times will be given in GMT on day 358.) PLAN ---- Continue running load DEC2203C. Finish obsid 3503, an HRC-S/LETG TOO observation of the supersoft X-ray source RX J0513.3-6951. Then two ACIS-S calibration observations of E0102-72 will complete this orbit. No Comm this shift.

NOTES/ISSUES/PROBLEMS NGST/FOT will be on vacation until Jan 5. Flight and ground ops will continue coverage. Next 9am meeting is Jan 5. Routine SOT shift reports resume Jan 5. From the 9am status meeting: Three supports in the past day. No issues. Three load segments uplinked, on-board loads good until 362:06:03. CAP 901 was run to replace the DEC2203B loads with DEC2203C loads. The latter provide for the 3 day gamma ray burst TOO, GRB031220, obsid 3905. Products for DEC2903B (two week load) were out last night. Load review is at 11am this morning on 405-244-5060 1165# EPHIN geometry is reading SMAL on the SOT snapshots, but EPHIN rates are quite low. No immediate explanation. Look aheads: ACA Dark current calibration on Jan 2 Earth observation of Jan 6 Installation of ONLS 3.9.4 being planned for Jan 14, 15. Have a happy and healthy New Year. ------------------------------------------------------- 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 -------------------------------------------------------
