Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 190 Issued at 2200Z on 09 Jul 2010
IA. Analysis of Solar Active Regions and Activity from 08/2100Z
to 09/2100Z: Solar activity was low. New Region 1087 (N18E72) was
numbered today and produced three C-class events. The largest of
these was a C3/Sf at 09/1951Z.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low. There is a chance for a C-class flare, and a slight
chance for a M-class event, from Region 1087.
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron
flux at geosynchronous orbit reached high levels today.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominantly quiet for the next three days (10-12
July).
