Proton Events: The greater than 10 MeV proton event that began on 30/0245 UTC remains in progress, peak flux was 108 pfu at 31/1620 UTC. C. Geomagnetic Activity Summary: The Geomagnetic field was at quiet levels. The >10 MeV proton event that began on 30/0245 UTC remains in progress, peak flux was 108 pfu at 31/1620 UTC. D. Stratwarm: Stratwarm alert exists. Major warming continues. The warming over the polar region is leading to a reversed temperature gradient between 50 and 3 HPA, with easterly zonal mean zonal winds from 10 to 2 HPA. E.
