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 283 Issued at 2200Z on 09 Oct 2000

IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z

Solar activity remained low. Region 9182 (N02W18) produced isolated subflares, the largest of which was a C5/1n at 09/1316 UTC. The subflares occurred near an area of emerging flux just to the west of this region. The remaining regions were stable. No new regions were numbered.
IB. Solar Activity Forecast
Solar activity is expected to remain low with a slight chance for an isolated M-class flare from Region 9182.
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
Geomagnetic field activity was at mostly quiet levels.
IIB. Geophysical Activity Forecast
Unsettled to active periods are possible during the first half of the period due to weak coronal hole effects. Otherwise, quiet to unsettled conditions are expected.
