Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 306 publicerat klockan 2200Z på 01 Nov 2000IA. Analys av solfläcksgrupper och solaktivitet från 31-2100Z till 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. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Regions 9212 and 9218 could produce isolated
M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 31-2100Z till 01-2100Z
Geomagnetic field activity was at quiet to unsettled levels.
IIB. Prognos för geofysisk aktivitet
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.
