B. Proton Events
None.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled with an isolated active period between 0300Z to 0600Z. The active conditions followed a period of southward IMF Bz. Solar wind plasma and magnetic field measurements indicate the presence of a weak coronal hole stream.
D. Stratwarm
None.
