Report of Solar-Geophysical Activity
Issued: 2007 Jul 09 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 190 Issued at 2200Z on 09 Jul 2007


IA. Analysis of Solar Active Regions and Activity from 08/2100Z
to 09/2100Z: Solar activity was low. Region 963 (S07E54) has
produced two C-class flares and numerous B-class flares. Region 963
grew slowly in size and complexity during the past 24 hours and is
now classified as a D-type group with 12 spots and a beta-gamma
magnetic configuration.
IB. Solar Activity Forecast: Solar activity is expected to remain
low, with a slight chance for an isolated M-class flare from Region
963.
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to become unsettled with a chance for active periods late
on day one (10 Jun) continuing through day two (11 Jun) in response
to a recurrent coronal hole. Conditions should decline to quiet to
unsettled on day three (12 Jun).
