Report of Solar-Geophysical Activity
Issued: 2008 Oct 16 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 290 Issued at 2200Z on 16 Oct 2008
IA. Analysis of Solar Active Regions and Activity from 15/2100Z
to 16/2100Z: Solar activity was very low with no flares observed.
Region 1005 (N26W29) was quiet and stable during the period. Region
1006 (S27W63) was numbered today and is an alpha magnetic
configuration. This region exhibits New Cycle 24 magnetic polarity.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z:
The geomagnetic field was mostly quiet. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be mostly quiet all three days of the forecast period
(17 - 19 October).
