Report of Solar-Geophysical Activity
Issued: 2008 Oct 09 2200 UTC
Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Weather Prediction Center and the U.S. Air Force.
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 283 Issued at 2200Z on 09 Oct 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 quiet. The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at quiet levels for 10-11 October. Unsettled to
active conditions with isolated minor storm levels at high latitudes
are expected for 12 October due to a recurrent coronal hole high
speed stream.
