Geomagnetic Activity Summary: The geomagnetic field was quiet to unsettled. Solar wind speed increased from approximately 360 km/s to 500 km/s, most likely due to a geoeffective coronal hole. A prolonged period of the southward Bz component was responsible for the unsettled conditions experienced. D. Stratwarm: None. E.
