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 334 publicerat klockan 2200Z på 30 Nov 2005IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity increased to moderate levels today.
Region 826 (S02E36) produced an impulsive M1 x-ray flare occurring
at 30/1752Z. White-light observations in Region 826, depict a
rapid growth phase in sunspot area since yesterday. This region has
also developed in magnetic complexity, with beta-gamma
characteristics evident. New Region 827 (N08E56) was numbered today
and is currently a simply structured beta group.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 826 is magnetically complex enough
to produce further isolated M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field was at predominantly quiet to unsettled levels.
A period of active conditions occurred at middle and high latitudes
between 30/0900 and 1200Z
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly unsettled to active levels. Minor
storm conditions with a chance of high latitude major storm periods
are possible on 01 and 02 December due to a recurrent high speed
coronal hole stream. A return to predominantly quiet to unsettled
levels is expected on 03 December as the coronal moves out of
geoeffective position.
