SOT shift report 2002-03-22 L974 Start at 2002:081:12:58 GMT = 2002 Mar 22 07:58 am EST End 11:00 am EST SOT Lead Ed Kellogg PLAN ---- CAL-ER 2002:081:11:36 CAL-ER 2002:081:21:23 RADIATION SUMMARY - Proton flux is high but falling. Measurement Observed Limit ----------------- -------- ----- ACE 2 hr fluence 1.8e7 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 0.4 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 5.5e8 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0. 10.0 P4GM (protons, 5.0 - 8.3 MeV): 0.7 300.0 P41GM (protons, 41 - 53 MeV): 0. 8.47 ACIS focal plane temperature -118.4 at 8:41 am EST. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 0 fids, 5 stars 1341 61251 LOS 1358 61251 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps a bit behind, because of a delay in acquiring data yesterday. Data loss - Load is good -> 084:06:05 CAPs - Next passes 2200, 0710, 1730 SIM note the safe mode SIM will be delayed until 2 Apr. because a battery in the EPS part of ASVT has problems. MP: Mar2502B load was approved yesterday. APR0102 products to be out today. S/C: There were OBC errors from - trying to disable SCS 105 when it was already disabled from the load. A related effect: the HRC door is now "more than mostly closed." This wasn't caught in the load review. Mike Juda will modify his checking scripts to catch this in the future. - a fixed point error, probably from stars; will be investigated. - "invalid HRC" that we always get. GOT: - DATA: - SOT: Proton rates are high but dropping. We observed a full halo CME beginning at 18:42 UTC 20 Mar., and another at ~04:00 UTC 21 Mar. in LASCO images (available thru 11:42 UTC 22 Mar.). Associated protons may reach the Earth on 23-24 Mar. GOES x-ray flux shows a long duration C class event at ~10:00 UTC 22 Mar. There is a high chance of a CME arriving within 96 hrs and a moderate chance of M or X class flares in the next 48 hours. MEETINGS: -------- Data ---- On colossus (/dsops/GOT/input), - Mar 21 21:28 2002_080_0941_080_2100_Dump_EM_61775.gz Evaluation of QL data --------------------- Target: OBSID SI SOT Eval. ---------------- -- --------- RXJ170930.2-263927obs3463 ACIS-S cc mode, OK NOTES/ISSUES/PROBLEMS --------------------- The ACIS temperature is a bit higher than usual for this part of the orbit. It's within spec, but may adversely affect CTI data validity.
