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 338 Issued at 2200Z on 03 Dec 2012IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z Solar activity has been at low levels for the past 24 hours.
The largest flare was a C1 observed at 03/0036Z from a region that has
not yet rotated around the east limb. There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be at very
low to low levels on days one, two, and three (04 Dec, 05 Dec, 06 Dec).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 381 km/s at
03/2032Z. Total IMF reached 13 nT at 03/1959Z. The maximum southward
component of Bz reached -7.5 nT at 03/2032Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels for the next three days (04 Dec, 05 Dec, 06 Dec).
