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.

expected to be at mostly unsettled conditions with isolated active
periods for 03 October. Quiet to unsettled levels are expected for
04-05 October.
