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 298 Issued at 2200Z on 24 Oct 2000IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity was low. Only a few small C-class flares
occurred. The most interesting event was a long-duration C2 which
peaked at 24/0932 UTC. Optical observations suggest that the source
of this event was beyond the southeast limb.
IB. Solar Activity Forecast
Solar activity is expected to be low.
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z
The geomagnetic field was quiet to active. The coronal hole
disturbance of the past day appears to be coming to an end.
IIB. Geophysical Activity Forecast
The geomagnetic field is
expected to be quiet to unsettled.
