Geomagnetic Activity Summary: The geomagnetic field was at unsettled to major storming levels. A magnetic storm gradually commenced after 04/0000 UTC, and sustained negative Bz resulted in minor and isolated major storm periods through 04/1500 UTC. Conditions abated to active and unsettled levels for the reminder of the day. D. Stratwarm: None E.
