Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels for 10-11 October. Unsettled to active conditions with isolated minor storm levels at high latitudes are expected for 12 October due to a recurrent coronal hole high speed stream. III.
