Analysis of Solar Active Regions and Activity from 24/2100Z to 25/2100Z: Solar activity was very low. No significant activity was observed over the past 24 hours. Region 944 (S08E37) is the only spotted region on the visible disk. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (26 - 28 February). Isolated active periods are possible on 26 February due to a recurrent coronal hole high speed stream. III.
