B. Proton Events
The greater than 10 MeV proton flux has been slowly increasing over the past 24 hours, apparently due to a backside solar event over the northwest limb. Current proton flux is about 6 pfu.
C. Geomagnetic Activity Summary
The geomagnetic field was quiet to unsettled.
D. Stratwarm
None
