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 306 Issued at 2200Z on 01 Nov 2000

IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity remained at low levels. Newly numbered Region 9218 (N18E39) emerged early in the period, then showed significant growth as it produced isolated C-class subflares. It was classed as a simply-structured D-type spot group as the period ended. Region 9212 (N10E22) showed an increase in spot count and a slight increase in magnetic complexity. It produced a single subflare during the latter half of the period. The remaining spot groups were stable. Four new spot groups were numbered today including Regions 9217 (S23W45), 9218, 9219 (N06E66), and 9220 (N08E75).
IB. Solar Activity Forecast
Solar activity is expected to be at low to moderate levels. Regions 9212 and 9218 could produce isolated M-class flares.
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
Geomagnetic field activity was at quiet to unsettled levels.
IIB. Geophysical Activity Forecast
Geomagnetic field activity is expected to remain at quiet to unsettled levels during the first two days. Active levels will be possible on the final day due to coronal hole effects.
