See https://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L9231. Start at 303:13:00 GMT PLAN ---- Return-to-science planned for the 2024:304:01:15:00 DSS-24 pass. Go/no-go discussion at 7pm on Slack #radiation-status channel. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 1 Supports Completed in the last 24 hours (Total time: 2.8 hours) 2 SSR dumps CAP's - 750AM, 303/0158z, Low Rate Dump of the Off-line OBC Checksummed Memory (XSUM_1) - 750AK, 303/0222z | Low Rate Dump of the Off-line OBC Checksummed Memory (XSUM_2) Radiation: The ACE P3 and GOES rates are still high and slowly decreasing. ACE P3 rates are currently at ~33,000. The HRC GOES Proxy is at ~60,000, comparable with the HRC shield trip limit. No CMEs expected in the next few days. Solar activity is expected to be moderate with a 30% chance for X-class flares on days one, two, and three (29 Oct, 30 Oct, 31 Oct). MP: Oct0324 return to science load review at noon today. A set of Matlab test loads out for a review by Friday. ENG: No issues. GOT: No issues.
