B. Proton Events
C. Geomagnetic Activity Summary
Quiet to unsettled.
D. Stratwarm
Stratwarm alert exists Saturday. As a result of the major warming, the circulation in the lower and middle stratosphere remains disturbed. Still, a reversed temperature gradient remains between 60N and the pole in the lower and middle stratosphere.
