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 317 Issued at 2200Z on 13 Nov 2006IA. Analysis of Solar Active Regions and Activity from 12-2100Z to 13-2100Z Solar activity was low. Region 923 (S05E07) produced a
C3 flare at 12/2155Z and a C1 flare at 13/0642Z. Much of the new
flux that emerged in the trailing portion of this region has now
decayed. A sunspot group rotated into view on the southeast limb and
was numbered today as Region 924 (S07E59). New sunspots emerged
southwest of this active region, which appear to be a separate
sunspot group.
IB. Solar Activity Forecast
Solar activity is expected to continue
at low levels. Isolated C-class flares are possible from Region 923.
IIA. Geophysical Activity Summary 12-2100Z to 13-2100Z
The geomagnetic field was quiet. Solar wind speed gradually declined
from 500 km/s to 410 km/s by the end of the period. The greater than
2 MeV electron flux at geosynchronous orbit was at high levels again
today.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet on 14 and 15 November. A recurrent high speed
stream is expected to rotate into a geoeffective position on 16
November and produce unsettled to active periods.
