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