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 038 publicerat klockan 2200Z på 07 Feb 2005IA. Analys av solfläcksgrupper och solaktivitet från 06-2100Z till 07-2100Z Solar activity remained at low levels. Newly numbered
Region 733 (S09E78) produced several low level C-class flares
during the period. There is a fair sized penumbral spot that has
just begun to rotate onto the visible disk. Due to the region's
proximity to the limb further analysis is pending. Region 732
(N09E57) was limited to the production of multiple B-class flares
over the period. Analysis indicates that there is a gamma magnetic
structure in both polarities of this active region. No other
regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low levels. Regions 732 and 733 are both capable of producing
further C-class flare activity.
IIA. Sammanfattning av geofysisk aktivitet 06-2100Z till 07-2100Z
The geomagnetic field was at quiet to minor storm levels. The ACE
spacecraft indicated that the onset of a recurrent high speed
coronal hole stream began around mid-day. Minor storm conditions
have persisted since 07/1430Z at middle and high latitudes.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to active levels with isolated minor
storm conditions possible through 8 February. Unsettled levels with
isolated active periods should dominate 9 and 10 February as the
geoeffective high speed coronal stream wanes.
