C. Geomagnetic Activity Summary
Geomagnetic activity was at quiet to minor storm levels. Quiet to unsettled conditions persisted until 11/1700 UTC when a 11 nT sudden impulse was observed. Active to minor storming conditions have persisted since the shock which is believed to be associated with the 09/1113 UTC M1/2f flare and CME.
