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
The greater than 10 MeV proton event remains in
progress with a start time of 16/0210 UTC and a peak flux of 5040
pfu observed at 17/1750 UTC. The greater than 100 MeV proton event
appears to have ended with a start time of 17/1215 UTC, 28 pfu peak
flux observed at 17/1700 UTC, and tentative end at 18/2205 UTC. GOES
spacecraft electron sensors and ACE SWEPAM instruments remain
affected by the energetic proton event.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from
active to severe storm levels.
