Geomagnetic Activity Summary: The geomagnetic field was mostly unsettled to active. There was an isolated minor storm period from 0900-1200 UTC. Solar wind data continue to indicate the presence of a high-speed wind stream, which is due to a favorably positioned coronal hole. The greater than 2 MeV electron fluxes reached high levels during the past 24 hours. D. Stratwarm: None E.
