B. Proton Events
C. Geomagnetic Activity Summary
The geomagnetic field was mostly quiet to active with isolated minor storm periods during local nighttime hours. The most active conditions early in the period were due to a waning high speed coronal hole stream. A weak transient passed the ACE spacecraft between 28/1400 - 1500Z. Predominantly southward Bz in the IMF resulted in active levels late in the period.
