Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 276 Issued at 2200Z on 02 Oct 2008
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity was very low.
IB. Solar Activity Forecast: Solar activity is expected to be very low.
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was at quiet to active levels. Observations from the ACE spacecraft indicate solar wind speeds averaging around 700 km/s.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at mostly unsettled conditions with isolated active periods for 03 October. Quiet to unsettled levels are expected for 04-05 October.
