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 336 Issued at 2200Z on 02 Dec 2014IA. Analysis of Solar Active Regions and Activity from 01-2100Z to 02-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
02/1555Z from Region 2222 (S19W10). There are currently 9 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (03 Dec, 04 Dec,
05 Dec).
IIA. Geophysical Activity Summary 01-2100Z to 02-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
648 km/s at 02/0259Z. Total IMF reached 10 nT at 01/2144Z. The maximum
southward component of Bz reached -10 nT at 01/2144Z.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (03 Dec,
04 Dec, 05 Dec).
