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 1 C class event was recorded yesterday.(http://www.dxlc.com/solar/) CMEs reported for past two days: January 23-25: No partly or fully earth directed CME observed.(http://www.dxlc.com/solar/- Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 2.36e+05 1/1523.4 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 5.54e-02 1/1715 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 1.09e-02 1/72 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 3.54E+05 1/2825 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

On Sunday, we patched SCS 104 to eliminate operation of mechanisms in HRC, with no problems in the patch. We did experience problems with console operation - the console operates slowly and for commands from scripts with parameters, must be buffered first. We also saw an anomaly in the checksum behavior: the OBC-A checksum changed autonomously from FACE after loading to OBC-B, and then changed back to FACE. We are investigating. GOT/IST: The emergency telecon number for off-hours is no longer 305-xxx-xxxx. We will now use the 405-244-5060, 1159# number for off-hours as well as during the working day. DATA:- SOT: Dan Schwartz requests that the testing of ONLS 10 include the pad time change. Ken Gage agrees to make that change. MEETINGS -------- The next quarterly will be Mar 3-4 AT MSFC.
