Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 026 Issued at 2200Z on 26 Jan 2009
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity continues at very low levels. The
visible disk was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field ranged from quiet to active levels. A recurrent
enhancement in solar wind speed began late on 25 January. Solar wind
speed increased from 280 km/s to about 380 km/s. A period of
sustained southward Bz between 26/1000 - 1600Z produced the most
disturbed periods.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active levels. Isolated active
periods, mostly at high latitudes, are expected on January 27.
Mostly quiet with isolated unsettled periods are expected on January
28 and 29.
