C. Geomagnetic Activity Summary
The geomagnetic field was at unsettled to active levels with an isolated quiet period from 0300 UTC to 0600 UTC. The coronal hole induced high speed solar wind stream continues. The greater than 2 MeV electron fluxes at geo-synchronous orbit reached high levels today.
