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 359 publicerat klockan 2200Z på 24 Dec 2000IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity increased to moderate levels, due to a
single M-class flare: an M1/Sf at 24/1115 UTC, from Region 9283
(S12E53). This region also produced several elevated C-class events
throughout the day, and exhibits notable growth in spot count, areal
coverage, and magnetic complexity since yesterday. Region 9280
(N09E80) remains the largest spot group on the disk, and also shows
some increase in magnetic complexity, though did not produce any
notable flare activity today. Two new regions were numbered:
9285 (N06E59) and 9286 (N30W47), with the former a source of some
subfaint C-class flare activity.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate for the next three days. Regions 9280 and 9283 are the
most likely sources of potential M-class activity.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was quiet at middle and high latitudes
throughout the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be predominantly quiet to unsettled. Some chance of
active levels exists for day one, due to a favorably positioned
coronal hole.
