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 327 publicerat klockan 2200Z på 22 Nov 2012IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
21/2116Z from Region 1618 (N08W13). Although this region retains weak
beta-gamma-delta magnetic characteristics, it has experienced
intermediate penumbral decay. All other regions on the disk remain
fairly stable. There are currently 5 numbered sunspot regions on the
disk.
IB. Prognos för solaktivitet
Solar activity is expected to be at low
levels on days one, two, and three (23 Nov, 24 Nov, 25 Nov).
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 417 km/s at
21/2303Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1200 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to begin the forecast period at mostly quiet levels until the arrival of
the 20 Nov CME midday on day one (23 Nov) when conditions are expected
to rise to active levels with a chance for minor storm periods.
Conditions have a chance for reaching major storm levels early on day
two (24 Nov) with the expected arrival of the 21 Nov CME. On day three
(25 Nov) conditions are expected to return to unsettled to active levels
due to CME combined with high speed stream effects.
