Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been at very low levels. The visible solar disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was at quiet levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels for the forecast period. There is a chance for an isolated period of unsettled conditions on day one (11 October), due to a recurrent coronal hole wind stream. III.
