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 2005 IA. Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity was moderate. Region 822 (S08E41) produced two M-class flares, an M1.0 at 2200Z and an M1.4 at 1751Z, along with numerous C- and B-class flares. Region 822 continued to grow, albeit at a slower pace. The region has retained its beta-gamma magnetic configuration. The remainder of the disk continues to be spotless.IB. Solar Activity Forecast
Solar activity is expected to be
moderate.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic field was mostly quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be predominantly unsettled for 16 November, with a
chance for isolated active periods. The elevated levels are
expected due to a sector boundary crossing and a favorably
positioned coronal hole. Unsettled levels are expected for 17-18
November.
