Shift L1582. Start at 324:13:00 GMT = 08:00am 20 Nov EST End 10:00am 20 Nov SOT Lead DAS (Times will be given in GMT on day 324.) PLAN ---- Continue running load NOV1703B. Do obsid 5249, an HRC-I calibration observation of the Vela Remnant to monitor the low energy QE. Then do obsid 4803, an ACIS-S observation of the OH gigamaser source RAS FSC 08201+2801, followed by perigee passage. No Comm this shift.

NOTES/ISSUES/PROBLEMS The scaled solar proton rates are high but falling. Will not be a concern for the remaining 4.5 ks of ACIS observing this orbit. We need to continue to be alert prior to resuming observations after perigee passage. Shanil reports "We had a short duration X1 flare early this morning. Shortly thereafter, the GOES >=10 MeV channel start rising as well as the GOES P2 channel (our EPHIN P4 predictor). After rising within an order of magnitude of its SCS107 trip level, it seems to have turned over." Tomorrow: Project telecon on ACIS contamination/bakeout. 10am EST From the 9am status meeting: Three supports in the past day, no issues. Last segment of NOV1703B was uploaded, so on-board loads good until 327:10:56. NOV2403B load approved yesterday. Includes observations of comet ENCKE, and a long observation of the 3rd most distant quasar known. FOT engineering team is continuing analysis of the putative Leonid meteor hit. SMF CCB will meet at 11am EST on 405 244 5060 1165# to kickoff discussion of ISATS replacement.
