B. 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
