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.

B. Proton Events
A slow, gradual rise in the greater than 10 MeV protons began soon after yesterday's M5 event. The 10 pfu alert threshold was finally reached at 14/0245Z. A second, larger influx of high energy protons followed today's X1 flare. The greater than 10 MeV proton flux were still slowly increasing at issue time, and the peak flux so far is 102 pfu at 14/2355Z.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to active. Solar wind speed remains elevated near 500 km/s, but is declining. The most disturbed geomagnetic periods occurred between 14/0100 - 1300Z when the IMF Bz was predominantly southward.
