Geophysical report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

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 MayA. Energetic Events

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.

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