See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L9013. Start at 085:13:00 GMT PLAN ---- At the day 84 17:55z comm (Sunday afternoon), SCS-107 was observed to have run at 084:11:34:34Z (7:34 EDT). This was in response to the arrival of a CME triggered by an X1.1 solar flare Friday night located near the Sun-Earth meridian. The science instruments were confirmed safe during the real-time communication pass. The current plan is to restart the science loads schedule at the 2024:86:03:00 Comm pass on DSS-56 (11:00 PM local time tonight). NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 8 Supports Completed over the weekend (Total time: 18.4 hours) 9 SSR dumps Loads good through: 2024:091:02:28:29 DSN DR's - C117809, DSS-36, DSN broke lock and reacquired. Radiation: The ACE P3 and HRC proxy have been declining from their peak values. The ACE P3 rate is now around 5,000 and the HRC proxy is now around 10,000. Both values are below their respective warning levels. Solar activity is expected to be moderate with a 85% chance for M-class flares and 25% chance for X-class flares on days one, two, and three (25 Mar, 26 Mar, 27 Mar). MP: Return to science loads are in work. ENG: No issues. GOT: No issues.
