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 296 Issued at 0245Z on 23 Oct 2011 This report is compiled from data received at SWO on 22 OctA. Energetic Events
Begin Max End Rgn Loc Xray Op 245MHz 10cm Sweep 1000 1110 1309 1314 N25W77 M1.3 Sf
B. Proton Events
A greater than 10 MeV proton enhancement was
observed in GOES 13 flux data associated with the long duration M1
flare at 22/1110Z from Region 1314, however the proton flux has not
reached the 10 PFU threshold.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet.
