Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity was very low with no flares observed. Region 1005 (N26W15) was quiet and stable during the period. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels all three days of the forecast period (16 - 18 October). III.
