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 319 Issued at 2200Z on 15 Nov 2006IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity was low. Region 924 (S08E28) produced a
C1 flare on 15/1901Z. This region was in decay, but new trailer
sunspots emerged late in the period. Region 923 (S05W20) still
maintains considerable size, but is in a slow decay phase. Region
925 (S05E38) is a small, simple beta group, which exhibited slight
growth.
IB. Solar Activity Forecast
Solar activity is expected to be low
to very low. Regions 923 and 924 have potential for isolated C-class
activity.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was quiet with isolated unsettled periods. 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 range from quiet to active. A recurrent high speed
stream is expected to produce occasional unsettled to active periods
over the next thee days.
