Proton Events: None C. Geomagnetic Activity Summary: The geomagnetic field ranged from quiet to major storm levels. ACE data indicates that a shock passed the instrument at approximately 16/2100Z. This transient is believed to have been the result of the full halo CME activity seen on 13 July. D. Stratwarm: None E.
