Report of Solar-Geophysical Activity
Issued: 2007 Jun 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 158
Issued at 2200Z on 07 Jun 2007
IA. Analysis of Solar Active Regions and Activity from 06/2100Z to
07/2100Z: Solar activity was low. Region 960 (S07W03) produced a few small
C-class events as it continued to slowly decay and simplify. Region 959
(S11W31) reemerged during the period, from a spotless plage to a simple
bipole with nine spots. Region 958
(S12W54) was quiet.
IB. Solar Activity Forecast: Solar activity is expected be low.
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet. The GOES greater than 2 MeV electron flux
attained high levels once again.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be
quiet throughout the forecast period.
