Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 336 Issued at 2200Z on 02 Dec 2009
IA. Analysis of Solar Active Regions and Activity from 01/2100Z
to 02/2100Z: Solar Activity was very low. No flares occurred during
the past 24 hours. The disk is spotless.
IB. Solar Activity Forecast: Solar activity is expected to be very
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for days one and two (03-04 Dec). Conditions
are expected to increase to quiet to unsettled levels with a slight
chance for isolated active periods as a recurrent coronal hole
becomes geoeffective early on day three (05 Dec).
