B. Proton Events
The greater than 10 MeV proton event continues in progress. The shock passage produced a very slight enhancement of the particle flux levels.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to minor storm. A shock in the solar wind was observed on ACE data at 04/1422Z. After the shock, the solar wind displayed high speeds. The shock and subsequent enhanced solar wind flow are most likely to have been produced by the combined drivers from CME's out of Region 9393 on 2 April.
