Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 040 Issued at 2200Z on 09 Feb 2010
IA. Analysis of Solar Active Regions and Activity from 08/2100Z
to 09/2100Z: Solar activity was moderate. Region 1045 (N23W26)
produced a M1/Sn event at 08/2123Z. This region has shown a slight
decay today but continues to maintain its magnetic beta-gamma-delta
IB. Solar Activity Forecast: Solar activity is expected to be low
to moderate with a slight chance for a X-class event from Region
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be unsettled with isolated active conditions for the
next three days (10-12 February). Activity is forecast due to the
recent CME activity from Region 1045. Late on 11 February into 12
February there is a slight chance for isolated periods of minor
levels due to the full halo CME observed on 06 February.
