C. Geomagnetic Activity Summary
The geomagnetic field ranged from quiet to minor storm levels. An isolated period of minor storm conditions existed at mid-latitudes from 13/0600 to 0900 UTC. Coronal hole high speed stream effects continued to be the main source of the elevated activity. The greater than 2 MeV electron flux at geosynchronous orbit exceeded event threshold at 13/1620 UTC, reached a maximum value of 1070 pfu at 13/1805 UTC, and fell below threshold value at 13/1810 UTC.
