Report of Solar-Geophysical Activity
Issued: 2007 Nov 08 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 312 Issued at 2200Z on 08 Nov 2007
IA. Analysis of Solar Active Regions and Activity from 07/2100Z
to 08/2100Z: Solar activity was very low. No flares were observed
during the past 24 hours and the solar disk continues to be
spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet during the past 24 hours. Solar wind
observations from ACE show a small increase in velocity, consistent
with a favorably positioned coronal hole. However, the change in the
solar wind has not been sufficient to increase activity levels above
quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the next three days (09-11 November).
