Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was very low. The visible disk remained spotless IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field was quiet to unsettled. The greater than 2 MeV electrons at geosynchronous orbit remained at high levels. The coronal hole high speed stream appears to be waning. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with a slight chance for an isolated active period on day one (October 30). Days two and three (October 31 - November 1) are expected to be quiet to unsettled. III. Event Probabilities 30 Oct-01 Nov Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
