Start at 114:13:00 GMT PLAN ---- Vehicle loads NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 8 Supports Completed over the weekend (Total time: 18.3 hours) 9 SSR dumps CAPs: - 593A, 113/2232z, Manual SCS-107 Activation to Safe the Science Instruments due to high radiation environment. - 1230L, 114/1132z, Manual ObsID Change Radiation: The ACE P3 exceeded safe limits on Sunday due to the passage of a CME associated with a filament eruption on Friday, and SCS 107 was run manually. The ACE P3 rates have dropped by approximately two orders of magnitude since the peak on Sunday and they have been relatively flat over the last 12 hours at the value of ~4000. Solar activity is expected to be low with a 25% chance for M-class flares on day one (24 Apr) and likely to be low with a chance for M-class flares on day two (25 Apr) and likely to be low on day three (26 Apr). MP: Return-to-science loads are in work and will be out tonight. ENG: Manual SCS 107 run was nominal. Vehicle loads running as planned. GOT: No issues.
