See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L8638. Start at 075:13:00 GMT PLAN ---- On vehicle loads. Resume science at the 11pm pass tonight. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 3 Supports Completed in the last 24 hours (Total time: 6.9 hours) 3 SSR dumps Radiation: Solar activity is expected to be very low with a chance for a C-class flares on day one (16 Mar) and expected to be very low with a chance for a C-class flares and a slight chance for an M-class flare on days two and three (17 Mar, 18 Mar). The ACE P3 flux has been dropping over the last 24 hours and at the current value of ~4,000 it is safe for the spacecraft. MP: Mar1723A return-to-science load review today at noon. ENG: No issues. GOT: No issues.
