Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was at very low levels. The visible disk remained spotless. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet during the forecast period (25 - 27 August). III.
