SOT shift report 2001-07-31 L740 Start at 2001:212:12:30 GMT = 2001 Jul 31 08:30 am EDT End 11:30 am EDT SOT Lead Ed Kellogg Plan: OBSID 00978, M 16 2001:211:19:12, ACIS-I NONE - THE M 16 Eagle Nebula STAR-FORMING REGION - image of the core of the Eagle Nebula to look for X-ray emission and flares from the stars and protostars. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 1.0e5 3.6e8. *ACIS* Orbital fluence (since perigee) 1.6e6 1.0e9. GOES-8/P2 4-9 MeV protons `P4GM' 0.07 95 GOES-8/p5 40-80 MeV protons `P41GM' 0.01 0.78 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): 0 300.0 P41GM (protons, 41 - 53 MeV): 0 8.47 ACIS focal plane temperature -119.7 at 9:31 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 3 fids, 5 stars 1300 978 Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Dumps current Data loss - Load is good -> 213/0915 CAPs - next passes 215/1941 (!! See discussion below) MP: The pending Genesis launch and GOES orbital operations are affecting our DSN pass schedule. We are trying to add a pass today and resolve a conflict on Thursday, to avoid any data loss. There also some uncertainty about procedures for having our pass requests accepted. We had a telecon with Pat Beyer this morning to relay our concerns. He will work these issues at JPL. Products are out for the AUG06 load; email review today. AUG13 OR received; we will begin work on it late this week. S/C: The mission directory is not getting loaded on some workstations. This is needed immediately. We couldn't log in on hoho. GOT: GOT is working both of the above problems. Data: No QL today. Some prelaunch data were inadvertently flowed to us yesterday during a JPL test of DSS27 automation, indicating Chandra in safe mode. This caused quite a stir at CXC until it was sorted out. SOT: Solar activity is very low. Proton flux is quite low. The snapshot is showing EPHIN geometry BAD some of the time. See below. MEETINGS: PCAD overview training @ 2:30. Data ---- On colossus (/dsops/GOT/input), - Jul 31 06:50 2001_211_1659_212_0231_Dump_EM_65688.gz Evaluation of QL data --------------------- OBSID Target SI SOT Eval. ----- ------ ------ ------- (none today) NOTES/ISSUES/PROBLEMS --------------------- EPHIN GEOM was reading alternately BAD and LARGE about every 5-6 minutes in the current snapshot series, which started at 2001:210:01:02:05 (Jul29). First BAD in current snapshot series is 2001:212:12:28:06 (Jul31). Back to LARGE at 2001:212:12:34:06 (Jul31). Flipped to BAD at 2001:212:12:40:10 (Jul31). Back to LARGE at 2001:212:12:45:04 (Jul31). Flipped to BAD at 2001:212:12:51:02 (Jul31). Back to LARGE at 2001:212:12:57:02 (Jul31). Flipped to BAD at 2001:212:13:03:02 (Jul31). Back to LARGE at 2001:212:13:09:03 (Jul31). Flipped to BAD at 2001:212:13:14:03 (Jul31). Back to LARGE at 2001:212:13:20:03 (Jul31). Flipped to BAD at 2001:212:13:26:02 (Jul31). Back to LARGE at 2001:212:13:31:03 (Jul31). Stayed at LARGE till last snap @ 2001:212:13:32:02 (Jul31).
