Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 019 Issued at 2200Z on 19 Jan 2009
IA. Analysis of Solar Active Regions and Activity from 18/2100Z
to 19/2100Z: Solar activity remained very low. Ephemeral Region 1011
(S12W25) emerged early in the period and was spotless by day's end.
It sported a few penumbraless spots at its peak and old Cycle 23
magnetic polarity. Little else of significance occurred or was
noted.
IB. Solar Activity Forecast: Solar activity is expected to stay
very low.
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z:
The geomagnetic field was quiet to active. A recurrent high-speed
solar wind stream brought short-lived active conditions to all
latitudes early in the day. The disturbance quickly waned, and quiet
conditions prevailed by the end of the interval.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet throughout the forecast period.
