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 222 publicerat klockan 2200Z på 09 Aug 2004IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z Solar activity was low. Today's activity consisted of
numerous C-class flares from Region 656 (S12E31). This region grew
rapidly during the past 24 hours and has formed into a compact
configuration that includes a magnetic delta configuration and also
is exhibiting magnetic shear along part of the inversion line. The
other two numbered regions on the disk were quiet and stable.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. Additional C-class flares are expected from Region 656.
There is a good chance for an isolated M-class flare from this
region over the next three days. There is a slight chance for a
major flare from this region as well, especially if the current
growth trend continues.
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
The geomagnetic field was mostly quiet to unsettled during the past
24 hours, with the exception of an active period from 0600-0900 UTC.
The enhanced activity corresponded to a solar sector boundary
crossing observed in the solar wind data.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be predominantly unsettled for the next three days
(10-12 August), with a slight chance for isolated active periods.
