Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was very low. There are no spotted regions on the visible disk. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field has been quiet to unsettled with a single active period due to a coronal hole high speed stream. Solar wind speed is currently 600 km/s. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active with the possibility of isolated periods of minor storming.
