Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to minor storm levels. Most of today's activity was quiet to unsettled. An isolated period of minor storming was observed between 21/0900-1200Z. Solar wind data indicated two sector boundary crossings during the past 24 hours, which may be related to the geomagnetic activity. D. Stratwarm: None E.
