SOT shift report 2003-05-29 L1407 Written at 2003:149:13:38 UTC = 08:38 am May-29-2003 EDT End 11:00:00 AM EDT SOT Lead: Ed Kellogg PLAN ---- OBSID 04175, FORNAX CLUSTER 2003:149:11:36, ACIS-I NONE RADIATION SUMMARY ----------------- Solar soft proton flux is High. (http://www.srl.caltech.edu/ACE/ASC/) We are close to the EPHIN trip point, but not there yet. Significant solar activity: Solar flare activity was high. A total of 15 C and 1 X class events was recorded during the day.(http://www.dxlc.com/solar/) CMEs reported for past two days: May 27: A full halo CME was observed starting at 07:42 UTC. The CME could reach Earth on May 29 but may be overtaken by another (larger and faster) CME. Another full halo CME was first observed at 23:50 UTC. This CME was associated with an X1.3 flare and will likely reach Earth during the latter half of May 29. May 29: Another full halo CME was observed early in the day after an X1.1 flare. This CME will probably arrive at Earth during the latter half of May 30.(http://www.dxlc.com/solar/, Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 4.08E+07 1/9 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 1.30E+01 1/7 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 1.26E-02 1/62 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 1.85E+08 1/5 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

The JUN09 load is in process. S/C: We tested long maneuver capability yesterday on ASVT. Errors are still ~1 degree. Some tweaking of coefficients is required. Today, we'll test safe mode recovery. There is a CAP review at 11:00 today. GOT/IST: DATA:- SOT: GOES x-ray flux: - there was another barely X class event early today. MEETINGS -------- CAP review at 11, FDB at 2.
