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 330 publicerat klockan 2200Z på 26 Nov 2003IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity was low. Occasional low C-class flares
were observed in Region 508 (S18W18). This region continues to
exhibit some complexity while undergoing slow decay. Region 501
(N04, L=004) has quietly rotated around the west limb. Region 507
(N08W30) maintains considerable size and still appears to contain a
weak delta configuration; however, activity in this region remains
very low. New Region 513 (N09E71) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. Though diminished greatly in size and complexity,
Region 508 still maintains potential for an isolated M-class event.
An M-class flare is also possible from Region 507.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was quiet to unsettled. Solar wind speed
remains elevated, but is in gradual decline. The greater than 2MeV
electron flux at geosynchronous orbit was at high levels again
today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to continue at quiet to unsettled levels. Isolated active
periods are possible at higher latitudes.
