Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 186 Issued at 2200Z on 05 Jul 2009
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity increased to low levels. Region 1024
(S27W13) produced a C2/Sf flare at 05/0713Z, as well as frequent
B-class flares. Minor changes were observed in the region since its
rapid emergence yesterday. It retained a beta magnetic structure
with some polarity mixing evident in its intermediate spots.
IB. Solar Activity Forecast: Solar activity is expected to be very
low. There is also a chance for an isolated C-class flare from
Region 1024.
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
Geomagnetic field activity was at quiet levels.
IIB. Geophysical Activity Forecast: Geomagnetic field activity is
expected to be at quiet levels throughout the forecast period (06 –
08 July).
