PLAN ---- OBSID 03863 1 SGR 1900+14 2003:153:12:26:54.979 25.0 ACIS-S NONE. NATURE OF THE TORQUE VARIABILITY IN SGR 1900+14. RADIATION SUMMARY ----------------- Solar soft proton flux is Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity: Not available; this report is prepared one delay later.(http://www.dxlc.com/solar/) CMEs reported for past two days: June 1-2: Several CMEs were observed off of the west and east limbs, all of them appeared to be the result of activity in limb regions.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 7.84E+01 1/4591837 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.00E-01 1/950 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 1.00E-02 1/78 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 4.60E+08 1/2 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

REAL TIME OBSERVATIONS UTC OBSID ---------------------- --- ----- - Notes from 9 am meeting ------------------------ OPS: Passes 9 over the last 3 day(s) Dump status Current Data loss None Load is good -> 157:06:30 UTC CAPs 820 150:22:12 Disable angular momentuim unloading. 675 150:22:14 Enable SCS 107. 851 150:22:31 Ground commanded ACIS CTI. Next passes 1220, 2250, 0800 MP: JUN0303 TOO load was approved. We are working on the JUN0903 TOO followup load. S/C: We had another SIM motor temperature high limit trip over the weekend. The gyro current is stable at ~140 mA.
