Joint USAF/NOAA Solar and Geophysical Activity Summary
SGAS Number 257 Issued at 0245Z on 14 Sep 2017
This report is compiled from data received at SWO on 13 Sep

B.  Proton Events:  The greater than 10 MeV proton flux reached S1
(Minor) levels with a peak flux of 98 pfu at 13/0630 UTC. The
greater than 100 MeV proton flux was below the 1 pfu
warning
threshold at the end of the period.
C.  Geomagnetic Activity Summary:  The geomagnetic field reached
minor storm conditions the first synoptic period, likely as
a
result of some influence from the 10 Sep far side CME. Levels
decreased to active, then to quiet as the period progressed.
