B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field ranged from unsettled to minor storm periods with isolated major storm levels at high latitudes. A gradual rise in the solar wind speed began early in the period, rising to a peak speed near 700 km/s, before gradually declining to near 550 km/s. The IMF Bz was predominantly southward during the first half of the period, which accounted for the most disturbed conditions. A greater than 10 MeV proton enhancement began soon after today's long duration M8 flare.
D. Stratwarm
None.
