SOT shift report 2003-04-21 L1369 Written at 2003:111:14:57 UTC = 10:57 am Apr-21-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04434, IGR J16358-4726 2003:111:03:49, ACIS-S NONE - Peculiar X-ray Transient IGR J16358-4726 - discovered on 03/19 2003 - period of 5860s, changing within the observation. This is a follow-up observation to quantify short term changes in the 5860s periodicity and perform phase resolved spectroscopy. RADIATION SUMMARY ----------------- Solar soft proton flux is Very Low. (http://www.srl.caltech.edu/ACE/ASC/) Significant solar activity yesterday: Solar flare activity was low. Only 1 C class event was recorded.(http://www.dxlc.com/solar/) CMEs reported for past two days: April 18-20: No obviously geoeffective CMEs observed.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 9.46E+04 1/3806 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 5.17E-02 1/1838 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 5.04E-03 1/155 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 4.58E+05 1/2183 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

Next passes 2010, 0600 MP: Last week's rapid replan resulted in using previously used OBSIDs for the ERs this week. We will do a replan to correct it. We'll uplink the new plan at 2010 UTC today. S/C: The gyro current was noisy yesterday, then dropped 10 mA to 140 and got quiet. On day 108 we tripped some limits. It looks like a glitch; maybe a single hit to the PEA memory. We will run the gyro swap procedure for record this afternoon. GOT/IST: - DATA: - SOT: GOES x-ray flux: There was a large spike in x-ray flux, up to M class, just about 12:25 UTC, during our morning meeting. It appears to be of short duration, but bears watching.
