Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity continues at very low levels. There was no significant activity observed this period. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field was quiet to unsettled. Solar wind speed increased to near 480 km/s as a coronal hole rotated into a geoeffective position. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet with isolated unsettled periods. III.
