SOT shift report 2002-09-06 L1142 Start at 2002:249:12:42 UTC = 2002 Sep 06 08:42 am EDT End 11:00 am EDT SOT Lead Ed Kellogg PLAN ---- CAL-ER 2002:249:12:44 then OBSID 02548, ONC FLANKING FIELD S 2002:249:13:12, ACIS-I NONE: the relationship between age, rotation, and X-ray activity in late type stars in Orion and NGC 2264 aged between ~1-10 Myr. Tomorrow, we have a lunar eclipse. The times are TLM contact 250:14:50-20:00 UTC (10:50 am - 4:00 pm EDT) Actual eclipse 250:15:55-16:34 UTC (11:55 - 12:34 EDT). We will have several engineers on console for this event. If there is a SCS 107 radiation shutdown during the eclipse, we will use prepared procedures that cover all envisioned cases for shutdown occurrence time in relation to the eclipse. RADIATION SUMMARY ----------------- Solar soft proton flux is very low, but rising slightly. There was a full halo CME yesterday. It probably will affect Chandra tomorrow, 7 Sept. or Sunday, 8 Sept. Radiation Measurement Observed Limit --------------------- -------- ----- ACE 2 hr fluence 2.9e5 3.6e8 GOES-8/P2 4-9 MeV protons `P4GM' 1. 95. GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 4.4e5 1.0e9 EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0.1 10.0 P4GM (protons, 5.0 - 8.3 MeV): 1. 300.0 P41GM (protons, 41 - 53 MeV): 0. 8.47 ACIS focal plane temperature -119.7 at 2:58 am EDT. REAL TIME OBSERVATIONS UTC OBSID ----------------------------------------------------------------- - Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss - Load is good -> 251:18:32 UTC CAPs - Next passes 1600 - uplink 2nd eclipse contingency patch 0000 0900 - uplink eclipse patch 1120 - 26m auto test 1450 - lunar eclipse operations 1625 - lunar eclipse operations, cont'd. MP: The SEP0902C load is in review. We will not be observing during the eclipse; appropriate stars could not be found. S/C: The eclipse will be a 30% occultation, at ~noon tomorrow EDT. An out of limit condition seen yesterday was a ground processing error. GOT: - DATA: - SOT: There was a long duration C5.2 event yesterday peaking at 17:10 UTC. A full halo CME was associated with this event. The CME expanded quickly eastwards and slowly over the west limbs. Although Earth will not receive a direct hit, parts of the CME are likely to reach Earth on September 8. High probability of CME to impact earth within 96 hours. Moderate probability of M and X class flares within the next 48 hours.
