Geomagnetic Activity Summary: The geomagnetic field was initially at unsettled levels but has been at active to minor storm levels since 08/0000 UTC and continuing through the end of the reporting period (08/2100 UTC). The geomagnetic field continues to be buffeted by a persistent high speed solar wind stream with velocities in the 700 to 800 km/s range and Bz values varying between -8 nT to +1 nT. The greater than 2 MeV electron fluxes continue to be at high levels. D. Stratwarm: None E.
