Shift L825. Start at 297:12:00 GMT = 08:00am 24 Oct EDT End 12:00 noon 24 Oct SOT Lead DAS (Times will be given in GMT on day 297.) PLAN ---- Continue running load OCT2301A. Finish ACIS-S observation SAX J1806.5-2215 a new X-ray source detected only during type I bursts, obsid 1916. Then do ACIS-S observations of the ultraluminous infrared galaxy IRAS 17208-0014, obsid 2035; a search for shadowing of the X-ray background by the cloud CHVC125, obsid 2484; and the distant sloan survey quasar SDSS094108+594725,obsid 3035.

ACIS focal plane temperature -119.9. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Load review for OCT2901B will be this afternoon at 2pm. Load is known to need star catalog replacements, but otherwise should be ready. Gyro 2 is showing noise in its current over the past two days, but not the out-of-spec bias jog which occured on Sunday. There will be a meeting and telecon at 11am EDT to discuss the bright star hold event. 405 244 5060 1165# There will be a meeting and telecon at 2:30pm EDT to discuss preparations and plans for the Leonid meteor shower which will occur on Nov 18. 405 244 5060 1165# Radiation is moderate, but at tolerable levels for ACIS. However, two CME on Tuesday may hit today or tomorrow. EPHIN rates larger than usual for this orbital position, but factors of 25 to 100 below trigger rates.
