Geomagnetic Activity Summary: The geomagnetic field was quiet to active. Mostly unsettled conditions prevailed early in the period in response to a waning high speed coronal hole stream. Solar wind data indicated another high speed stream onset at around 1300Z, preceded by a weak co-rotating interaction region. Solar wind speed ranged from 500 - 550 km/s for the latter half of the period and isolated active periods were observed at all latitudes. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels. D. Stratwarm: None E.
