Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 191 Issued at 2200Z on 09 Jul 2008
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels for 10 July. Unsettled to active conditions, with isolated minor storm periods, are expected for 11-12 July. An increase in activity is expected due to a recurrent coronal hole high speed stream.
