SOT shift report 2002-08-20 L1125 Start at 2002:232:12:33 UTC = 2002 Aug 20 08:33 am EDT End 11:00 am EDT SOT Lead Ed Kellogg PLAN ---- We resumed with the AUG1902D load: OBSID 04361.We are now doing CAL-ER 2002:232:08:24. The next observation is in ~8 hr. RADIATION SUMMARY ----------------- Low energy proton flux is still elevated, but decreasing. There was a major M5.0 flare at 01:40 yesterday with an associated CME. We don't yet know if it will hit earth. Radiation Measurement Observed Limit --------------------- -------- ----- ACE 2 hr fluence 2.6e7 3.6e8 GOES-8/P2 4-9 MeV protons `P4GM' 1. 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 1.8e9 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0.8 10.0 P4GM (protons, 5.0 - 8.3 MeV): 29.6 300.0 P41GM (protons, 41 - 53 MeV): 0.0 8.47 ACIS focal plane temperature -119.9 at 5:45 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- none Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps current Data loss - Load is good -> 236:11:00 UTC CAPs 617 @ 231:18:29 UTC to enable RADMON & SCS 107 Next passes 1700, 1800, 0255 MP: We resumed the load yesterday: AUG1902D. We canceled the AUG2020A load plan. The AUG2602A load is in review. We are doing an ACA earth constraint test presently. S/C: There was one violation of limits yesterday: a memory load reject. We add it to the list of these occasional events. GOT: - DATA: - SOT: There were several lesser flares yesterday. There were several impulsive X-ray flux enhancements in the past 24 hrs. Moderate probablility of CME to impact earth within 96 hours. High probability of M and X class flares within the next 48 hours.
