There have been no earth-directed CMEs in the past three days. Measurement Observed Limit ----------------- -------- ----- ACE 2 hr fluence 5.3e5 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 0.2 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 2.1e6 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0.0 10.0 P4GM (protons, 5.0 - 8.3 MeV): 0.4 300.0 P41GM (protons, 41 - 53 MeV): 0.0 8.47 ACIS focal plane temperature -119.7 at 1:59 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- 3 fids, 5 stars 15:00 2885 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last 1 day(s) Dumps current Data loss - Load is good -> 130:08:00 UTC CAPs - Next passes 1500, 2305 MP: The May13 products will be out today; email review. S/C: No issues. GOT: - DATA: - SOT: Five C class and one M class flares yesterday; two C flares were long duration events. GOES x-ray flux is presently low, but showed two long duration enhancements yesterday, associated with the flares. A full halo CME was observed in LASCO C3 images beginning at 14:18 UTC on May 6 at the east limb. Its source was likely well behind the east limb. Not likely to hit earth. Low probablility of CME to impact earth within 96 hours. Moderate probability of M and X class flares within the next 48 hours. MEETINGS: -------- Jeff Holmes' class will be at 12-2 pm.
