Joint USAF/NOAA Solar and Geophysical Activity Summary

SGAS Number 144 Issued at 0245Z on 24 May 2013 This report is compiled from data received at SWO on 23 May

B. Proton Events
A greater than 10 MeV proton flux greater than 10 pfu event continues. The event began at 23/2330Z, reached a maximum of 1660 pfu at 23/0650Z, fell below the 1000 pfu threshold at 23/1040Z and ended the day at 180 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled.
D. Stratwarm
Not available
E. Daily Indices: (real-time preliminary/estimated values)

Daily Proton Fluence (flux accumulation over 24 hrs)
GT 1 MeV 2.3e+08   GT 10 MeV 6.9e+07 p/(cm2-ster-day)
(GOES-15 satellite synchronous orbit W135 degrees)
Daily Electron Fluence
GT 2 MeV 2.00e+08 e/(cm2-ster-day)

F. Comments
  >2MeV electron data suspect because of proton
contamination.  GOES-15 particle data is being used because of a
GOES-13 outage.
