Proton Events: None 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. E.
