Mission Planning (Dan): - AUG1701B load approved last night, segment with eclipse commands uplinked - Science commanding in second segment - HRC did not get required products to complete review of AUG1701B last night due to an oversight. Products made available and were reviewed this AM. - Will run ASVT simulation today (recover from safe mode) - Review AUG20 load today at 2pm S/C Engineering(Jeff): - S/C OK, eclipse load onboard and running. - Will verify first part of eclipse commanding in 1800 comm (2pm EDT) SOT(Bill): - Proton radiation levels peaked early this AM and have been decreasing since then - Electron levels still slowly decreasing since peak at 228:0000 - EPHIN P4GM was at about 40 last pass, E1300 was at 6.7 and has been decreasing and P41GM is at about 3 and also decreasing. - Decision to be made at 1:45 EDT telecon whether or not to resume science. EPHIN levels typically must be below 1/3 of triggers, although they are not there yet it looks possible that they will be by later on today. DSOPS(Jen): - QL of obsid 1900, was interrupted by SCS 107. GOT(Peter): - No issues - Split string for simulation - Netap server will be shutdown 6:30am Sunday. Will verify that all is well after restarting Meetings/events: - 9:30am, CAP review - 10am, SIM pre-brief - 1:45pm, radiation tagup 3) Quick look data: Seq # ObsID It Target start time SI Grat Comment ---------------------------------------------------------------------------------------------------------- 300048 01900 00 CAL 83 2001:227:16:17:51.649 93.8 HRC-S LETG
