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 001 publicerat klockan 2200Z på 01 Jan 2005IA. Analys av solfläcksgrupper och solaktivitet från 31-2100Z till 01-2100Z Solar activity has been high. Region 715 (N05E21)
produced an X1.7 at 01/0031 UTC with an associated Type IV radio
sweep and a Type II radio sweep (760 km/s). A Coronal Mass Ejection
(CME) may have been produced in association with this flare, but
could not be confirmed due to the unavailability of solar imagery.
Region 715 has decayed slightly in size and magnetic complexity, and
now maintains a beta-gamma configuration. No new regions were
numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be low
to moderate. Region 715 may produce M-class and isolated X-class
flares.
IIA. Sammanfattning av geofysisk aktivitet 31-2100Z till 01-2100Z
The geomagnetic field has been quiet to active. The greater than 2
MeV electrons at geosynchronous orbit reached high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to active levels all three days. Active
conditions are expected on 2-3 January from the effects of a
geoeffective coronal hole high speed solar wind stream, and from
potential effects of CME shocks associated with the M-class flares
observed 30 and 31 December. Isolated minor storming mid-day on 3
January and into 4 January is possible from a CME shock associated
with today's X-class flare. Activity should subside late on 4
January to quiet to unsettled levels.
