Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 253 Issued at 2200Z on 10 Sep 2010
IA. Analysis of Solar Active Regions and Activity from 09/2100Z
to 10/2100Z: Solar activity was very low. The visible disk was
spotless. An area of enhanced plage and surging was observed on the
east limb near S20.
IB. Solar Activity Forecast: Solar activity is expected to remain
at very low levels.
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: Solar activity is expected to
be at predominately quiet to unsettled levels for the next three
days (11 – 13 September) due to a sequence of small, recurrent
coronal holes that are forecasted to become geoeffective. Isolated
active periods are possible on 12 – 13 September.
