SOT shift report 2001-09-28 L799 Start at 2001:271:12:42 GMT = 2001 Sep 28 08:42 am EDT End 11:00 am EDT SOT Lead Ed Kellogg PLAN ---- Instruments safed under high solar radiation. Restart load Sunday, Sept. 30 at 1:00 am EDT. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 8.6e7 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 6. 95 GOES-8/P5 40-80 MeV protons `P41GM' 0.15 0.78 *ACIS* Orbital fluence (since perigee) 0 1.0e9. EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 31.9,SMALL 10.0 P4GM (protons, 5.0 - 8.3 MeV): 418.7,SMALL 300.0 P41GM (protons, 41 - 53 MeV): 2.3,SMALL 8.47 ACIS focal plane temperature -119.9 at 03:14 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps current Data loss none Load is good -> no load CAPs none Next passes 1655, 0015, 1820, 0110 MP: We plan to restart the load at 273/0500. The load will contain the last observation in the previous load, plus all of OCT01, and will be called SEP01. Load review for SEP30 today at noon. S/C: A look at day 269 shows no gyro current nor bias changes. We see yellow limit violations associated with our current attitude: low bus current, DPA. Nothing to be concerned about. GRETA 1.1.1 was approved by fdb yesterday - will be moved from dev->ops early next week. We tested SSR scripts on ASVT. GOT: - DATA: - SOT: Proton flux is high from previous X flare, and dropping steadily. A partial halo CME occurred on 27 Sep. 1213 UT. The CME could have geoeffective extensions. At the 9:15 meeting, the ops team decided to go ahead with the load restart as mentioned above.
