Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to unsettled, before an isolated minor storm occurred between 14/1500-14/1800, as the result of the onset of coronal hole, high speed stream effects. Active conditions followed the minor storm before returning to unsettled conditions by the end of the period. D. Stratwarm: Not Available E.
