Analysis of Solar Active Regions and Activity from 12/2100Z to 13/2100Z: Solar activity was very low. New Region 938 (N02E61) was numbered today. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on 14 January. On 15 January, quiet to unsettled conditions are expected. On 16 January, a recurrent coronal hole high speed stream is expected to become geoeffective causing active to minor storm conditions. III.
