Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 311 Issued at 2200Z on 07 Nov 2009
IA. Analysis of Solar Active Regions and Activity from 06/2100Z
to 07/2100Z: Solar activity was very low. Region 1030 (N25W25)
decayed into a spotless plage region today. No flares were observed
during the past 24 hours.
IB. Solar Activity Forecast: Solar activity is expected to be very
IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet to unsettled, with a slight chance for an
active period at high latitudes, on day one (08 November). The
increase in activity is due to a weak recurrent coronal hole
high-speed stream. Quiet levels are expected on days two and three
(09-10 November).
