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 059 publicerat klockan 2200Z på 28 Feb 2004IA. Analys av solfläcksgrupper och solaktivitet från 27-2100Z till 28-2100Z Solar activity has been low. There were several B- and
C-class X-ray events during the period. Region 564 (N15W54) has had
no significant changes from yesterday and continues to have a good
potential to produce a major flare. There are an additional four
regions each classified as Beta magnetic configuration, that have a
fair potential to produce a major flare. Region 568 (S16W20) was
newly numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be
mostly low with a chance for isolated moderate. There remains a
good potential for Region 564 to produce a major flare.
IIA. Sammanfattning av geofysisk aktivitet 27-2100Z till 28-2100Z
The geomagnetic field has been mostly quiet to active with an
isolated period of minor storming at 0900 UTC.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to active levels with a fair chance for
periods of minor storming through 2 March, due to the influence of a
high-speed solar wind stream.
