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

B. Proton Events
The greater than 10 MeV proton event that began
at 08/0215 Z and reached a peak flux of 1880 pfu at 11/0425 Z is
still in progress and has declined to near 10 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was at
active to major storm levels. A shock was observed by the ACE
spacecraft at approximately 12/0600 UTC. Solar wind speed at ACE
increased to over a thousand km/s; however, the IMF Bz never went
lower than -12 nT. Minor to major storm levels occurred at all
latitudes following the shock. Solar wind speed gradually declined
to near 800 km/s by the end of the period.
