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 112 publicerat klockan 2200Z på 22 Apr 2011IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity was moderate. Region 1195 (S18E28)
produced two M-class flares: an M1/Sn at 0457Z and an M1/1n at
1553Z. There was not any indication of a CME associated with either
of these events. Region 1195 dominated the activity during the past
24 hours and produced numerous additional C-class x-ray events. The
group showed steady growth throughout the period and is currently
estimated to have 370 millionths sunspot area. The group also shows
some magnetic complexity (Beta-Gamma); particularly interesting is
an east-west section of the inversion line in the center of the
group which has a favorable configuration for building shear. Region
1193 (N17W45) is gradually decaying and did not produce any flares.
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate for the next three days. Additional M-class flares are
likely from Region 1195, especially if it continues to grow.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic field was generally quiet during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet for the next three days (23-25 April).
