Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity has been very low. There are no numbered regions on the active disk. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field has been quiet to unsettled, with one period of isolated active conditions. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with isolated active conditions possible all three days from the effects of a recurrent high speed solar wind stream.
