SOT shift report 2001-08-01 L741 Start at 2001:213:12:35 GMT = 2001 Aug 01 08:35 am EDT End 11:30 am EDT SOT Lead Ed Kellogg Plan: OBSID 02492, CI AQL 2001:213:12:52:08.874 19.7 ACIS-S NONE - THE RECURRENT NOVA CI AQL - expected to emit soft x-rays during an interval after the ejected shell has become optically thin and before the hydrogen shell-burning ceases and the white dwarf cools. RADIATION SUMMARY Observed Limit ----------------- -------- ----- ACE 2 hr fluence 3.5e7 3.6e8. *ACIS* Orbital fluence (since perigee) 9.1e7 1.0e9. GOES-8/P2 4-9 MeV protons `P4GM' 0.1 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): 0.1 10.0 P4GM (protons, 5.0 - 8.3 MeV): 0.2 300.0 P41GM (protons, 41 - 53 MeV): 0 8.47 ACIS focal plane temperature -119.7 at 7:14 am EDT. REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- (none) Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss - Load is good -> 213/0013 CAPs - next passes 2120, 1650 Genesis launch scheduled for 12:31 EDT today with a two min window, 20% chance of adequate weather. Next window 24 hrs later. MP: We got an additional pass yesterday. If Genesis launch slips, we may get an added pass today. Pat Beyer at JPL identified Holg(er) Schroeder as our contact for establishing better DSN scheduling working relationships. Ken is preparing an email to Holg. The email load review went well yesterday. Ken will rerun it today; no timing changes expected. Sitdown review will probably be tomorrow. Regression testing of OFLS 9.1b gave an unexpected result. Kevin is investigating. S/C: We had a thruster valve temperature yellow flag. This is minor; will be investigated. ASVT testing of the Bright Star procedure is continuing. We are doing a test this AM, 10 - ~12 to support JPL's validation of 26 meter upgrade equipment. SIM data will be flowed. GOT: - Data: No QL today. SOT: Solar activity is low. Proton flux increased to within 1/10 of threshold for ACE, but is now steady. The EPHIN geometry BAD readings seen yesterday were from an older version of the snapshot software. The more recent one from MTA does not show BAD readings for the same time period. MEETINGS: Star working group, 10:00. Data ---- On colossus (/dsops/GOT/input), - Aug 1 06:16 2001_212_1219_213_0013_Dump_EM_66116.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 min in /pool14/chandra/chandra.snapshot yesterday. This is not the best data source. We have now switched to http://cxc.harvard.edu/mta_days/MIRROR/Snap/snap.cgi, which does not have that problem.
