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 307 publicerat klockan 2200Z på 02 Nov 2000IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z Solar activity was low. Region 9218 (N19E26) produced
several minor C-class events. Region 9218 (N19E26) grew
significantly in area since yesterday but maintained a simple beta
magnetic configuration. An EPL occurred on the northwest limb at
approximately 02/1744Z. Further analysis is required as data
becomes available. SOHO/LASCO imagery indicated an earth-directed
full halo CME from a filament eruption east of Region 9214
yesterday at approximately S17E39. The CME was first visible above
the SE limb at 01/1626Z. The imagery suggests most of the material
and energy associated with the CME is directed to the southeast.
However, evidence of a weak full halo is clear. No new regions were
numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
The geomagnetic field was quiet.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled the first day. Due to the
expected arrival of the earth-directed full halo CME mentioned
above, active conditions are expected on the second day of the
period. Minor storm levels are possible in the higher latitudes.
The geomagnetic field is expected to decrease to predominantly
unsettled conditions toward the end of the period.
