B. Proton Events
The greater than 100 MeV proton event at geosynchronous orbit that began at 07/0405Z, reached a maximum of 69 pfu at 07/1525Z, and was in progress at the close of the period. The greater than 10 MeV proton event that began at 07/0510Z, reached a maximum of 6530 pfu at 08/1115Z, and was in progress at the close of the period.
C. Geomagnetic Activity Summary
Geomagnetic field activity ranged from quiet to major storm levels. Activity increased from quiet levels to active to major storm levels following a geomagnetic sudden impulse at 08/1105Z (59 nT, Boulder USGS magnetometer).
