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 356 publicerat klockan 2200Z på 22 Dec 2003IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z Solar activity was low. The largest flare this period
was a C5/Sf from Region 528 (N09E23). This region was responsible
for several other smaller C-class flares. Mixed polarities are
obvious in the central and trailing portions of this spot group,
where most of the activity is occurring. Isolated low C-class flares
also occurred in Region 530 (S21E50). Region 525 (N08W10) continues
to exhibit some mixed polarities, but remains relatively quiet. New
Region 531 (N01W21) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low.
There is a small chance for an M-class flare from Regions 525 and
528.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
The geomagnetic field was unsettled to active. Solar wind speed
remains elevated, ranging 600 - 650 km/s since late on 21 December.
This high speed stream is associated with a well positioned
transequatorial coronal hole. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels for a brief period
today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet to unsettled with isolated active levels
through 23 December. The high speed coronal hole stream that is
creating this disturbance should begin to subside on the 23rd.
Mostly quiet to unsettled levels are expected on 24 - 25 December.
