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 287 Issued at 2200Z on 14 Oct 2001IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity was low. Only a few, small C-class
flares were observed, mostly in Region 9661 (N15E30). This remains
the largest sunspot group on the visible disk and has maintained its
beta-delta magnetic configuration. New Regions 9666 (S12E31) and
9667 (N24E73) were numbered.
IB. Solar Activity Forecast
Solar activity is expected to be low
to moderate. Region 9661 appears to be capable of an isolated major
flare.
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
