SOT shift report 2001-08-10 L750 Start at 2001:222:12:45 GMT = 2001 Aug 10 08:45 am EDT End 11:30 am EDT SOT Lead Ed Kellogg PLAN ---- OBSID 01895, GAMMA CAS 2001:222:09:37, ACIS-S HETG - HIGH RESOLUTION X-RAY SPECTROSCOPY OF GAMMA CASSIOPEIA...a unique Be X-ray source with erratic "shots," a hard spectrum, and a high flux level between that of single Be stars and the Be/X-ray binaries...study the properties of the temperature, density, composition, bulk motions and ionization processes in the circumstellar environment of this unusual hot star. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 7.9e6 3.6e8. GOES-8/P2 4-9 MeV protons `P4GM' 20 95 GOES-8/P5 40-80 MeV protons `P41GM' 0.01 0.78 *ACIS* Orbital fluence (since perigee) 2.8e7 1.0e9. EPHIN rates (cts/cm^2-s-sr) OBSERVED RADMON limit ---------------------------------------- -------- ----------- E1300 (electrons, 2.64 - 6.18 MeV): 0 10.0 P4GM (protons, 5.0 - 8.3 MeV): 87.7 300.0 P41GM (protons, 41 - 53 MeV): 0 8.47 ACIS focal plane temperature -119.7 at 9:34 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1255 1895 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps Data loss - Load is good -> 224/1102 CAPs - next passes 2230,0520 Discovery launch: Aug 10 5:15 pm. Multi-Purpose Logistics Module Leonardo, crew rotation. MP: There is an issue about whether to leave the TOO observation of WZ Sge in the AUG13 load because it may be too faint to see. Fred Seward is examining the ACIS data, and will make a decision later today. There will be an email review of the AUG20 load on Monday. Ken and Darrell will be at the JPL DSN meeting next week, and will learn more about plans for DSS automation testing. S/C: There is an issue with putting the plots on the website. It's about passwords not working. GOT: Will work on the plotting issue. Will conduct DTF testing this AM, then ASVT testing. DATA: Joy gave a report to Roger on status of data obtained in the first two weeks of the mission. SOT: Lasco and EIT observed a PARTIAL HALO CME on 2001/08/09. Proton rose dramatically, but still below thresholds. 60 -100% chance of CME hitting earth in the next 96 hrs. "A CME could impact Earth on August 12 and cause active to major storm conditions." - http://www.dxlc.com/solar/.
