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 288 publicerat klockan 2200Z på 15 Oct 2002IA. Analys av solfläcksgrupper och solaktivitet från 14-2100Z till 15-2100Z Solar activity was at moderate levels. Region 149
(N14W07) produced the largest event of the period, an M1/1f flare
occurring at 15/1422 UTC. A filament from central meridian through
the southern hemisphere erupted shortly before this flare and is
believed to have been the trigger for the event. SOHO/LASCO imagery
depicts an associated CME to the event which does not appear to be
earth directed. No significant changes were noted today in the spot
group or the magnetic complexity to this region. Region 140
(S08W52) produced a C1/Sf flare at 15/1326 UTC. Newly numbered
Region 161 (N06E00) was assigned today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 149 has the potential of producing
low level M-class flares.
IIA. Sammanfattning av geofysisk aktivitet 14-2100Z till 15-2100Z
The geomagnetic field was at quiet to active levels. A slow, yet
steady, increase in the solar wind speed along with intermittent
periods of southward Bz allowed for the active periods seen today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to remain at quiet to active levels. Weak CME passage
effects may occur in response to the solar activity that occurred on
the 14th and may begin on day one and continue into day two of the
forecast period.
