Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 014 Issued at 2200Z on 14 Jan 2001
IA. Analysis of Solar Active Regions and Activity from 13/2100Z
to 14/2100Z: Solar activity was low. Mostly optically uncorrelated
minor C-class events occurred during the period. Region 9306
(N12W25) did produce a C8/Sf at 14/0254Z. Region 9306 continued to
show growth and is currently an Fac beta-gamma sunspot group with
over 500 millionths of white light area and approximately 60 spots.
No new regions were numbered today.
IB. Solar Activity Forecast: Solar activity is expected to be low
with an increasing chance of M-Class activity from Region 9306.
IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet to unsettled. A flilament erupted on
the northwest limb at approximately 14/0430Z. This event and the
associated CME following was observed in the SOHO/LASCO imagery. At
this time, most of the energy from this CME does not appear
earth-directed.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled.
