Geomagnetic Activity Summary: The geomagnetic field ranged from active to severe storm levels. A single K=7 period was observed at Boulder from 11/0300-0600 UTC. Solar wind conditions of high speed (700-800 km/s) and low density (about 2 p/cc) suggest that the expected coronal hole high-speed stream has arrived. D. Stratwarm: None E.
