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 303 publicerat klockan 2200Z på 30 Oct 2010IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity was very low. Region 1117 (N20W72)
produced several B-class flares. The largest of these was a B6 flare
at 30/1333Z. Region 1117 continued to show decreases in areal
coverage and sunspot count. New Region 1120 (N39E69) was classified
as a Bxo-beta spot group and produced a B2/Sf flare at 30/0728Z.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low to low levels, with a slight chance for an M-class event
from Region 1117.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field was predominantly quiet, with a single period
of unsettled levels. The greater than 2 MeV electron flux at
geosynchronous orbit remained at high levels during the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be predominantly quiet, with unsettled periods possible
at high latitudes late on day one (31 October). Activity is expected
to increase to quiet to active levels, with a slight chance for a
minor storm period at high latitudes, on day two (01 November) due
to a recurrent coronal hole high-speed stream. Quiet to unsettled
levels, with active periods at high latitudes, are expected on day
three (02 October).
