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 265 Issued at 0245Z on 22 Sep 2015 This report is compiled from data received at SWO on 21 SepA. Energetic Events

B. Proton Events
The greater than 10 MeV proton flux almost
completely recovered to background levels from a 3pfu enhancement on
20 Sep, following the west limb CME associated with the M2 flare
from Region 2420.
C. Geomagnetic Activity Summary
The geomagnetic field began at a
pair of periods with unsettled levels, before decreasing to quiet
conditions for the remainder of the day.
