Analysis of Solar Active Regions and Activity from 11/2100Z to 12/2100Z: Solar activity continues at very low levels. There are no sunspots on the visible disk. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled. Solar wind speed is expected to become slightly enhanced as a coronal hole rotates into a geoeffective position. Expect occasional unsettled periods on 14 September. III.
