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 325 publicerat klockan 2200Z på 20 Nov 2012IA. Analys av solfläcksgrupper och solaktivitet från 19-2100Z till 20-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event, with an
associated Earth-directed CME (estimated velocity of 664 km/s), observed
at 20/1241Z. There are currently 7 numbered sunspot regions on the disk.
Region 1618 (N08E14) has retained its beta-gamma magnetic complexity.
New Region 1620 (S08E59) was numbered.
IB. Prognos för solaktivitet
Solar activity is expected to be at
moderate levels on days one, two, and three (21 Nov, 22 Nov, 23 Nov).
IIA. Sammanfattning av geofysisk aktivitet 19-2100Z till 20-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
461 km/s at 20/1958Z. Total IMF reached 7.8 nT at 19/2347Z. The maximum
southward component of Bz reached -7.2 nT at 20/1725Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1277 pfu.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is expected
to be at mostly quiet levels for the next three days (21 Nov, 22 Nov, 23
Nov). Protons have a slight chance to cross alert threshold on days one,
two, and three (21 Nov, 22 Nov, 23 Nov) due to expected solar flare
activity from Region 1618. Further analysis is needed to determine the
geoeffectiveness of todays CME.
