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 325 publicerat klockan 2200Z på 21 Nov 2001 **********CORRECTED COPY**********IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z Solar activity has been low. Region 9704 (S17W24) was
the sole source of all the optical activity, and remains the largest
and most magnetically complex region on the visible disk. The
largest event of the period was a C6/Sf at 21/1818 UTC. A more
significant, long duration C4/Sf occurred during 21/1207-1650 UTC,
with peak flux observed at 21/1458 UTC. This event was accompanied
by a Type-IV radio sweep, and an associated filament eruption at
approximately N35W10. By 21/1406 UTC, a full halo CME was evident
in SOHO/LASCO imagery. New Region 9712 (N13E71) was numbered today
as it rotated into view on the east limb.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate.
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
The geomagnetic field was quiet to unsettled.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled through 23 November. A shock
arrival is expected early on 24 November, in association with the
CME activity described in section 1A above. Geomagnetic field
activity is expected to increase on that date, with isolated minor
storm periods possible.
