SOT shift report 2002-09-05 L1141 Start at 2002:248:12:55 UTC = 2002 Sep 05 08:55 am EDT End 11:00 am EDT SOT Lead Ed Kellogg PLAN ---- CAL-ER 2002:248:11:37 to 248:17:52 RADIATION SUMMARY ----------------- Chandra is in the rad zone. Solar soft proton flux is very low. There was a hard x-ray enhancement, C class, occurring a few minutes ago. It was of short duration; it probably will not affect Chandra. Radiation Measurement Observed Limit --------------------- -------- ----- ACE 2 hr fluence 1.5e5 3.6e8 GOES-8/P2 4-9 MeV protons `P4GM' 0.03 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.008 0.78 *ACIS* Orbital fluence (since perigee) (rad) 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): (rad) 10.0 P4GM (protons, 5.0 - 8.3 MeV): (rad) 300.0 P41GM (protons, 41 - 53 MeV): (rad) 8.47 ACIS focal plane temperature -117.0 at 9:33 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- no fids, 7 stars, last one not tracking 1313 61047 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps current Data loss - Load is good -> 251:18:32 UTC CAPs 806 @248:12:30 UTC. Short eclipse patch. Next passes 2100, 0600 Note: GRETA processing had an error due to VCDU end point. Recalculation solved the problem. MP: The SEP0902B load is out; sit-down review today @ 1:00. S/C: There was a small shift in roll bias, ~0.1 arcsec/sec. this is expected, but we haven't seen one in a while. GOT: - DATA: - SOT: Little flaring activity yesterday. Low probablility of CME to impact earth within 96 hours. Moderate probability of M and X class flares within the next 48 hours. MEETINGS -------- IAR today. FOT all hands today @ 3:00. FOT MP meets with CSC @ 2:00.
