Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 192 Issued at 2200Z on 11 Jul 2009
IA. Analysis of Solar Active Regions and Activity from 10/2100Z
to 11/2100Z: Solar activity continued very low. The disk is now
spotless as Region 1024 is past west limb at S25.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field has been quiet. Although the solar wind speed
has been elevated from recent times to near 450 km/s, the IMF is
weak and, therefore, of little stimulus to the magnetosphere.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to remain quiet throughout the forecast period.
