Issued: 2007 Oct 07 2200 UTC
Prepared jointly by the U.S. Dept. of Commerce, NOAA,
Space Environment Center and the U.S. Air Force.
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 280 Issued at 2200Z on 07 Oct 2007
IA. Analysis of Solar Active Regions and Activity from 06/2100Z
to 07/2100Z: Solar activity was very low. Region 972 ((S06W19) is a
Bxo spot group. This region remains the only numbered spot group on
the solar disk.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
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 quiet.
