See http://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L6626. Start at 254:12:56 GMT PLAN ---- Return to science planned for early Wednesday using 11pm EDT Tuesday (9/12) comm as the last uplink opportunity. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 9 Supports completed over the weekend (total time: 20.7 hours) 8 SSR dumps Loads good through: 2017:256:02:20:03 SCS 107 ran due to radiation near 254:07:51:39 and it shut down science operations. CAP 1432, 251/2003z: Command 4 CCD ACIS CTI via RTS post SCS 107 Run. Radiation: Yesterday afternoon region 2673 produced an X8 X-ray flare followed by a powerful solar proton storm. Proton rates are expected to remain high for the next 48 hours. Solar activity is expected to remain high with a chance for X-class flares on day one (11 Sep) and expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on day two (12 Sep) and expected to be very low with a slight chance for a C-class flare on day three (13 Sep). MP: SCS 107 recovery products are expected to be out later on today. They will include a recently approved TOO. Eng: SCS 107 ran nominally. Clean up actions at the next pass include CAPs to disable SCS 29, change of ObsID, warm boot ACIS. GOT: No issues.
