Analysis of Solar Active Regions and Activity from 30/2100Z to 31/2100Z: Solar activity was very low. No flares were detected. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet through the forecast period. III.
