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 events was recorded yesterday. (http://www.dxlc.com/solar/) CMEs reported for past two days: Feb. 14-16: No partly or fully earth directed CME observed.(http://www.dxlc.com/solar/- Jan Alvestad) Radiation Measurement Observed Observed/Limit --------------------- -------- -------------- ACE 2hr fluence 82389 1/4369.5 (http://www.srl.caltech.edu/ACE/ASC/) GOES-10/P2 4-9 MeV protons `P4GM' 0 1/1715 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) GOES-10/P5 40-80 MeV protons `P41GM' 0 1/206 (ftp://ftp2.sec.noaa.gov/pub/lists/pchan/G10pchan_5m.txt) *ACIS* Orbital fluence (since perigee) 8.02E+05 1/1247 (http://asc.harvard.edu/mta/alerts/current.dat) EPHIN rates (cts/cm^2-s-sr) at last comm.

The intercept is Thursday morning, so they hope to have the load review later today. The new load probably won't be ready for the regular 2:00pm load review time. S/C: No new limits tripped. Momentum dump went nominally. No reported issues GOT/IST: Nothing to report DATA:-Nothing unusual to report SOT: - Low radiation levels. Only possible radiation issue is a coronal hole that could possibly spawn a CME. MEETINGS -------- 11:30am SOT -MP meeting today due to holiday yesterday.
