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 322 publicerat klockan 2200Z på 17 Nov 2000IA. Analys av solfläcksgrupper och solaktivitet från 16-2100Z till 17-2100Z Solar activity remained at low levels. Region 9231
(S24E19) produced isolated C-class subflares. It stabilized as a
medium-sized F-type group with moderate magnetic complexity. Region
9235 (N14E51) also produced isolated C-class subflares. A 32-degree
filament erupted from the southwest quadrant beginning around
17/0700 UTC. A CME was associated with the eruption, but it was not
Earth-directed. No new regions were assigned.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 9231 may produce isolated M-class
flares during the period.
IIA. Sammanfattning av geofysisk aktivitet 16-2100Z till 17-2100Z
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit was at moderate to high
levels.
IIB. Prognos för geofysisk aktivitet
Geomagnetic field activity is
expected to be at quiet to unsettled levels during the first day
increasing to unsettled to active levels during the rest of the
period due to coronal hole effects. The greater than 2 MeV electron
flux is expected to remain at moderate to high levels.
