SOT shift report 2003-06-04 L1413 Written at 2003:155:16:10 UTC = 11:10 am Jun-04-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID CAL-ER. Momentum unload this afternoon. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. . (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Solar flare activity was low. A total of 5 C class events was recorded during the day.(http://www.dxlc.com/solar/) CMEs reported for past two days: June 1-3: No obviously geoeffective CMEs observed.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 2.68E+06 1/134 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.03E-01 1/922 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 1.05E-02 1/74 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 1.54E+07 1/65 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm. OBSERVED RADMON limit, or observed/limit ---------------------------------------- -------- ----------------------------- E1300 (electrons, 2.64-6.18 MeV): 0.0 10 P4GM (protons, 5-8.3 MeV): 0.0 300 P41GM (protons, 41-53 MeV): 0.0 8.47 (http://cxc.harvard.edu/cgi-gen/mta/Snap/snap.cgi?action=Latest) ACIS focal plane temperature -119.7 C, at 08:39 am EDT (http://acis.mit.edu/asc/acisrt.html) REAL TIME OBSERVATIONS UTC OBSID ---------------------- --- ----- No fids, five stars being tracked. Last two slots not getting good star data. 1235 60715 Notes from 9 am meeting ------------------------ OPS: Passes 4 over the last 1 day(s) Dump status Current Data loss None Load is good -> 158:13:00 UTC CAPs - Next passes 155/2150-0000 DSS 27 156/0900-1100 DSS 27 MP: JUN0903 load will be reviewed at 2 pm today. S/C: We will unload momentum today at 5:50 pm. We are starting from a cold temperature to minimize the chance of a thruster anomaly. The gyro is quiet. Dan Shropshire and Eric will be on ASVT this afternoon, testing the safe mode recovery IRU swap. GOT/IST: DATA: The TOO for obs3920 was processed through level 2 and delivered to Peter Ford at 4 am. They will be examining the data to determine if any changes are needed to the setup for the followup TOO obs 3921. SOT: We held a CAP review for: CAP 830, momentum dump; CAP 831, halt momentum dump. Both were approved.
