Solar activity report
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 342 Issued at 2200Z on 08 Dec 2010IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z Solar activity was very low.
IB. Solar Activity Forecast
Solar activity is forecast to be very
low for the next 3 days (09-11 December).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast
The geomagnetic field is
forecast to be mostly quiet day 1 (09 December), quiet to unsettled
on day 2 (10 December), and quiet to unsettled with the chance for
active conditions on day 3 (11 December). Activity is forecast due
to recurrent coronal hole effects anticipated to begin late on day 2
(10 December).
