Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was very low. A new cycle sunspot group was numbered today as Region 1013 (N26E20). IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was at quiet to unsettled conditions. Solar wind speed during the past 24 hours has averaged around 440 km/s with interplanetary Bz between +6/-6 nT. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominately quiet for the next three days (25-27 February). III.
