Analysis of Solar Active Regions and Activity from 23/2100Z to 24/2100Z: Solar activity was at low levels. Region 1149 (N16W45) produced a C1 flare at 24/0615Z. Region 1149 is currently a Dsi-beta group, with a significant drop in spot count. Region 1147 (N24W49) produced a few low-level B-class flares and remains an Hsx-alpha group. IB. Solar Activity Forecast: Solar activity is expected to be very low to low, with a slight chance for an isolated M-class flare. IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic field was at quiet levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels, with isolated unsettled levels possible at high latitudes, for the next three days (25-27 January). III.
