Analysis of Solar Active Regions and Activity from 29/2100Z to 30/2100Z: Solar activity was at very low levels. New Region 921 (S06E58) was numbered today. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 29/2100Z to 30/2100Z: The geomagnetic field was quiet to active. Solar wind speed at ACE has decreased from approximately 600 km/s to 490 km/s. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled. III. Event Probabilities 31 Oct-02 Nov Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
