C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to major storm levels. A strong shock was observed at ACE at 21/1614 UTC. This was followed by a sudden impulse at 21/1645 UTC (measured as 15 nt on the Boulder magnetometer). The sudden impulse was followed by minor (21/1500-1800 UTC) and major (21/1800-2400 UTC) storm levels.
