Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was very low. The visible solar disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field began the day with a brief episode of minor storming but quickly subsided to quiet to unsettled conditions as the influence of the coronal hole high speed stream diminished. The greater than 2 MeV electron flux reached high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field conditions are expected to range from quiet to unsettled on day one (October 31), becoming predominantly quiet for the remainder of the period (November 1-2).
