Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 026 Issued at 2200Z on 26 Jan 2010
IA. 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.
