Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity was very low. No significant activity was observed during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for the next three days (13 - 15 August). III.
