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.
