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 037 publicerat klockan 2200Z på 06 Feb 2005IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity remained at low levels today. Region
732 (N09E70, believed to be old Region 720) was numbered today and
was the source for the largest flare of the period, a C1 x-ray flare
that occurred at 06/0939Z. Analysis of the magnetic field structure
indicates a fair amount of complexity over a large are of plage
while the sunspot area coverage is currently meager. New Region 731
(S02E27) was also numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels. Region 732 could continue the production of C-class
flare activity.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
The geomagnetic field was at quiet to active levels. The active
conditions occurred between 06/0600 and 0900Z due to the associated
solar sector boundary crossing that was seen at the ACE spacecraft
at approximately 06/0500Z.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to active levels with a chance for
isolated minor storming for 7 February due to a recurrent coronal
hole high speed stream. Predominantly unsettled conditions are
expected on 7-8 February as the coronal hole wanes.
