SOT shift report 2002-06-14 L1058 Start at 2002:165:12:46 UTC = 2002 Jun 14 08:46 am EDT End 10:30 am EDT SOT Lead Ed Kellogg PLAN ---- OBSID 03185,A907 2002:165:07:54, ACIS-I NONE - A907 has revealed sharp features in the X-ray brightness distribution that may be shock fronts. This exposure will provide an accurate temperature profile across these features and a definitive answer to this question. RADIATION SUMMARY ----------------- Solar proton flux is low. There were no flares nor CMEs yesterday. Radiation Measurement Observed Limit --------------------- -------- ----- ACE 2 hr fluence 9.3e5 3.6e8 GOES-8/P2 4-9 MeV protons `P4GM' 0.08 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 1.3e7 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): 0.0 300.0 P41GM (protons, 41 - 53 MeV): 0.0 8.47 ACIS focal plane temperature -119.7 at 6:48 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- 3 fids, 7 stars 1255 3185 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps current Data loss - Load is good -> 169:10:54 UTC CAPs - Next passes 2110, 0445, 1340 MP: We are working on installing OFLS 9.3 on the prime system. We expect to finish this morning. We plan to use it for the JUN24 scheduling. Products will be out Monday. S/C: The Flight Director's Board approved starting work on the patch to the gyro scale factor. The board also closed out the EPHIN glitch counter anomaly. GOT: - DATA: - SOT: Congratulations to the Chandra team from George Ricker, PI of the GRB TOO 020531, on our excellent and timely work arranging the observation and processing the data. This is the very first short GRB promptly localized with sufficient accuracy to permit sensitive multi-wavelength followup searches. No flares yesterday! I can't remember when this has happened in the past! X-ray flux very quiet Low probablility of CME to impact earth within 96 hours. Low probability of M and X class flares within the next 48 hours. MEETINGS: -------- FOT all hands next Tuesday at 10 am for results of TRW West & EK thermal analysis study.
