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 320 Issued at 2200Z on 15 Nov 2000IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z Solar activity decreased to low levels. Isolated
C-class flares occurred, the largest of which was a C5/1b at 15/0246
UTC from Region 9223 (S14W61). The visible regions were mostly
stable with no significant growth or decay noted. New Region 9234
(N20E22) was numbered.
IB. Solar Activity Forecast
Solar activity is expected to be at
low to moderate levels. There is a fair chance for isolated M-class
activity during the period.
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit was high.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is
expected to be at quiet to unsettled levels. The greater than 2 MeV
electron flux at geosynchronous orbit is expected to decline to
normal to moderate levels during the latter half of the forecast
period.
