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 356 publicerat klockan 2200Z på 22 Dec 2002IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity increased to moderate levels. Region
223 (N25W58) produced an M1.1/2f flare at 22/0230 UTC that had an
associated Type II radio sweep with an estimated shock velocity of
833 km/sec and a Tenflare. There was some growth in areal spot
coverage during the period while this region continues to exhibit a
simple magnetic structure. Regions 226 (S28E67) and 229 (N19W42)
have been in steady decay throughout the period. Region 226
continues to depict a magnetic delta structure in the main cluster
of intermediate spots. Region 230 (S08W07) underwent little change
today. The later three regions mentioned were quiescent during the
period. No new regions were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic field was at quiet to unsettled levels with an
isolated active period at middle and high latitudes between 22/1800
and 2100 UTC. The NASA/ACE instrument detected a weak shock passage
at approximately 22/1300 UTC. The Bz component of the
interplanetary magnetic field has been predominantly north since
transient onset. The greater than 2 MeV electron flux at
geosynchronous orbit reached moderate levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels through
the forecast period. Due to a slightly elevated solar wind speed
there may be isolated active periods observed mostly at high
latitudes into day one of the period.
