Analysis of Solar Active Regions and Activity from 18/2100Z to 19/2100Z: Solar activity was very low. No flares were observed. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: Geomagnetic field activity was at quiet to unsettled levels. 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 at mostly quiet levels during the period (20 - 22 October). III.
