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 296 publicerat klockan 2200Z på 23 Oct 2001IA. Analys av solfläcksgrupper och solaktivitet från 22-2100Z till 23-2100Z Solar activity was at high levels. The largest flare
for the period was from Region 9672 (N18E00), which produced an
M6/1b flare at 23/0223 UTC and an M1/Sn flare at 23/0023 UTC. The
magnetic beta-gamma-delta configuration appears to have grown
stronger since the latest M-class flare occurrence from this region.
Multiple C-class flares were observed during the period. Region
9676 (N14E30) produced a C7/1f at 23/0803 UTC and Region 9678
(N07E48) produced several minor C-class flares early in period.
Three new regions were numbered today, Region 9678, Region 9679
(S10E58), and Region 9680 (N22E61).
IB. Prognos för solaktivitet
Solar activity is expected to remain
at moderate to high levels. Region 9672 continues to show a strong
delta magnetic configuration.
IIA. Sammanfattning av geofysisk aktivitet 22-2100Z till 23-2100Z
The geomagnetic field was at quiet to active levels with an isolated
period (23/0300 to 0600 UTC) of minor storm conditions at USAF
planetary. The greater than 10 MeV proton flux event at
geosynchronous orbit exceeded threshold at 22/1910 UTC, and reached
a maximum of 24 pfu at 22/2130 UTC. The event ended at 23/0115 UTC.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to major storm levels. The M6/2n and the
X1/2b flares from Region 9672 (that occurred during the last
forecast period) have both produced CME activity on LASCO/EIT
imagery. Analysis indicates that both shock arrivals may occur
between the early and middle period of day one resulting in storm
conditions to occur on day one and two of the forecast period.
