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 033 publicerat klockan 2200Z på 02 Feb 2004IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z Solar activity was low. There were two C-class flares
during the past 24 hours, a C2 at 0759 UTC from Region 547 (S09W26),
and a C1 at 1124 UTC from a region very close to the east limb at
latitude N05. Region 547 and 549 (N14E42) are the largest groups on
the disk but are still relatively small and stable. Region 550
(S08W14) and Region 551 (S06E63) were assigned today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
for the next three days (2-4 February). There is a slight chance for
an isolated M-flare from Region 547 or Region 549.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field ranged from quiet to major storm levels. An
initially quiet to unsettled condition gave way to about six hours
of storming between 0600-1200 UTC. The storming was associated with
high speed solar wind and some moderately negative interplanetary
magnetic field component Bz (-5 to -10). The field has been mostly
active since 1200 UTC. The solar wind speed has shown a slowly
increasing trend since 0500 UTC. The greater than 2 MeV electron
fluxes reached high levels.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to active for the next two days (3-4
February), and should decline to mostly unsettled with occasional
active periods for the third day (5 February). The enhanced activity
is expected from favorably positioned coronal holes.
