Report of Solar-Geophysical Activity
Issued: 2008 Jul 10 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 192 Issued at 2200Z on 10 Jul 2008
IA. Analysis of Solar Active Regions and Activity from 09/2100Z
to 10/2100Z: Solar activity has been very low. The visible solar
disk remains spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be at unsettled to active levels for 11-12 July with a
chance for isolated minor storm conditions possible due to a coronal
hole high speed stream. Activity levels for 13 July is expected to
be mostly unsettled levels with a chance for isolated active
periods.
