C. Geomagnetic Activity Summary
The geomagnetic field was quiet to active. There were some indications in the ACE satellite data of a weak interplanetary shock passage at about 13/0100 UTC. Active geomagnetic conditions and an isolated period of minor storming at higher latitudes followed, and persisted for several hours until mainly unsettled conditions developed from about 13/1200 UTC onward. This disturbance is presumed to have originated from the CME activity of 9 September.
