Analysis of Solar Active Regions and Activity from 30/2100Z to 01/2100Z: Solar activity was low. Region 875 (S11W33) produced a long-duration C1/sf flare at 01/1535Z. Region 876 (S15W07) produced a B9/sf flare at 01/0157Z. A Type II radio sweep, with an estimated shock speed of 436 Km/sec was associated with this flare. IB. Solar Activity Forecast: Solar activity is expected to be low. IIA. Geophysical Activity Summary 30/2100Z to 01/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominantly unsettled. Intervals of active conditions are possible. III.
