B. Proton Events: None
C. Geomagnetic Activity Summary: The geomagnetic field was at quiet
to active levels with one period of minor storm conditions. A shock
passage was observed by the NASA/ACE spacecraft at 01/0425 UTC and a
corresponding 26 nT sudden impulse was recorded at 01/0511 UTC on
the Boulder magnetometer. Active to minor storm conditions
followed the sudden impulse.
D. Stratwarm: None
