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 279 publicerat klockan 2200Z på 06 Oct 2001IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z Solar activity was moderate due to a single M-class
event during the period. An optically uncorrelated M2 flare occurred
at 06/0525 UTC. This event also produced a Coronal Mass Ejection
(CME) off of the sun's west limb as seen in LASCO imagery. This CME
should not be geoeffective. Region 9641 (S13W48) produced a C3/1f
flare at 05/2120 UTC. This event also produced a south-west oriented
CME. Again, this CME should not be geoeffective. The only other
activity of note during the period was a C3/1f flare from Region
9648 (S07E22).
IB. Prognos för solaktivitet
Solar activity is expected to be
mostly low with an isolated chance of an M-class flare.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
The geomagnetic field was at quiet to unsettled conditions. The
greater than 10 MeV proton flux at geosynchronous orbit remained at
elevated levels but below the proton event threshold of 10 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly quiet to unsettled conditions. Active
conditions are possible on the third day due to a recurrent coronal
hole and its resulting high stream impacting earth.
