Analysis of Solar Active Regions and Activity from 25/2100Z to 26/2100Z: Solar activity was very low. Region 1042 (N18W86) produced several B-class events during the past 24 hours, the largest of which was a B6.7 at 1751Z. Region 1041 (S24W03) was quiet and stable during the last 24 hours. IB. Solar Activity Forecast: Solar activity is generally expected to be very low for the next three days (27-29 January). There is a chance of an isolated C-class event from either Region 1041 or 1042. IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic field has been quiet for the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain quiet for the next three days (27-29 January). III.
