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.
