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 331 publicerat klockan 2200Z på 26 Nov 2004IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity has been very low. A long duration B4
event was observed at 25/2321 UTC. Analysis of image data does not
reveal the apparent optical flare associated with this event.
Region 707 (S16E42) has grown in both white light coverage and
sunspot count and is currently a beta-gamma magnetic configuration.
A new region was numbered today as Region 708 (N08E81), which is
likely the return of old Region 696 (N09,L=026). This region
produced numerous events during its last rotation before exiting the
west limb on 12 November, including two X-class flares.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low. Several regions on the disk are capable of producing
C-class events.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was at quiet to active levels. Solar wind
speeds at ACE has shown a steady decline in the past 24 hours and is
currently around 420 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled.
