No loads running due to SCS-107 trip yesterday. Were running NOV0103A, which was uploaded Friday night. 107 trip data: SCS-107 was triggered autonomously on rad-zone exit at ~2003:306:20:38 and ran nominally. Spacecraft attitude is good for several days with momentum as limiting constraint. More time is needed to observe the current trends in radiation before a replan start time can be set. Next meeting to discuss radiation and replan following the 9AM daily ops tag-up (405-244-5060 1159#). Radiation telecon summary: 3 X-class flares in last 24 hours, hard proton storm and soft protons starting to rise. ACE P3(primary soft proton monitor, 115-193keV) and P2 channels have gone bad, either temporarily or permanently. P5 has also been corrupted, but may be OK again as of now. Onboard radiation monitors are also very high now. E1300 360.8 (10.0 trip) P4GM 2379.4 (300.0 trip) P41GM 2.6 (8.47 trip) Steve O'Dell has developed the following scale factors to estimate P3 flux from P5 or P6: P3 ~= 50*P5 P3 ~= 200*P6 These can be used for P3 estimates in the short term, pending a more complete analysis. A "Plan A" replan was defined as follows: - Resume observations after next radiation zone exit, at about 309/1130Z - GO/NOGO comm would be at 309/0750-0850Z - Plan for an ACIS CTI by inserting a stop science at the beginning of the load - Try to extend the 309/0750 comm to get a more current realtime look at onboard radiation levels, before making final GO/NOGO decision - Replan load will include 4678, 3699-3702 cals. MP will work with SOT MP on details. Since we have lost our direct ACE P3 monitor we need to work up a revised monitoring and alert system. Scott, Shanil and Rob will meet today at 10:30 to kick this activity off. In the short term we can use Steve's scale factors for predictions. Next radiation discussion after tomorrow's 9am meeting (unless events warrent).

9 supports over weekend, all 34m - 3 SCS loaded from NOV0103A, not running now - CAPs run: 617 305/0347 Enable SCS-107 and RADMON 892 305/0405 Ground commanded ACIS CTI - Dumps current Mission Planning (Ken): - NOV0103A signed off, uploaded Friday night. - Observewd TOO (5240) plus 4216 before SCS-107 ran, just before start of 4912 S/C Engineering(Dan/Paul P.): - One unusual error was observed in SCS-107 run. Attributed due to ACIS being commanded when 107 ran.Its not a problem - Paul P noted that ACIS needs a warm re-boot to reload the patched software, since ACIS loaded old software from onboard ROM. ACIS will meet to go over the event and recovery in an 11am meeting. Will need a CAP to run several recovery SOP's. SOT(Bill): - See above notes on radiation.
