Shift L1586. Start at 328:13:00 GMT = 08:00am 24 Nov EST End 10:00am 24 Nov SOT Lead DAS (Times will be given in GMT on day 328.) PLAN ---- Continue running load NOV2403D. This is the replan for continuity, following the restart after Friday's radiation shutdown. Observing Comet 2P/Encke, obsid's 5253-5281 with ACIS-S, as a multi-pointing observatino to follow the moving comet.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Ten supports over the weekend. No issues. Observing program stopped via CAP 593 at 326:01:24:54 last Friday due to high solar proton fluxes. About 100ks of scheduled observing time was lost. Load NOV2203A was uplinked Saturday to maneuver to the Leonid antiradiant, and then to perigee momentum mangement configuration. CAP 675 re-enabled SCS 107 and the science observing program was resumed with NOV2403D, obsid 4846 at 328:01:16. On-board loads are good until 331:30:35. DEC0103 needs a re-run for continuity to NOV2403D. Products expected late today for load review tomorrow. Discussion of possible moon observations at 11am EST today, on 405 244 5060, 1165#. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 4007 NGC 4486B 325:09:07 ACIS-S NONE Target not obvious 4008 NGC 4564 325:19:33 ACIS-S NONE Target not obvious 4016 NGC4419 326:01:09 ACIS-S NONE partial, interrupted by SCS 107. Target not obvious 4846 NGC 5283 328:01:16 ACIS-S NONE Partial. 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 -------------------------------------------------------
