There was a major M5.4/2B flare at 01:57 UTC today, that will likely cause low energy proton flux increases in the next day or so. Radiation Measurement Observed Limit --------------------- -------- ----- ACE 2 hr fluence 7.8e6 3.6e8 GOES-8/P2 4-9 MeV protons `P4GM' 4. 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.1 0.78 *ACIS* Orbital fluence (since perigee) 3.2e8 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 1.3 10.0 P4GM (protons, 5.0 - 8.3 MeV): 11.4 300.0 P41GM (protons, 41 - 53 MeV): 0.7 8.47 ACIS focal plane temperature -119.7 at 5:24 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1302 3291 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss - Load is good -> 238:00:00 UTC CAPs - Next passes 2300, 0730 MP: AUG2602C products ready for signature. SEP02 being processed. There will be a 40 minute long lunar eclipse during this load. We plan to observe through it, a target 90 degrees to the Sun. A thermal gradient will develop across the OBA during the eclipse, but the periscope will be OK and the fidlights can compensate for any misalignments. S/C: The lunar eclipse patch testing on ASVT was successful yesterday. GOT: - DATA: - SOT: There was an X flare yesterday at 05:34 UTC, and a M5.4/2B flare at 01:57 UTC today with associated impulsive X-ray flux enhancements. Moderate probablility of CME to impact earth within 96 hours. High probability of M and X class flares within the next 48 hours.
