Proton Events: None. C. Geomagnetic Activity Summary: The geomagnetic field was quiet to active with an isolated period of minor storm conditions during the 14/0900-1200 UTC synoptic period, due to a combination of waning negative polarity CH HSS effects and a prolonged period of -Bz associated with the probable arrival of the 10 Apr transient feature.
