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 003 publicerat klockan 2200Z på 03 Jan 2002IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z Solar activity was at moderate levels. The largest
flare of the period was optically uncorrelated, an M1 occurred at
02/2148 UTC. Region 9767 (S23E23) produced a C5/1f at 03/0220 UTC
that had an associated radio sweep with an estimated shock velocity
of 410 km/s. LASCO imagery doesn't depict the presence of an
associated halo with this event. Although this region has been
spotless for several days, Region 9758 (N13W84),produced several Sf
optical flares today. Other activity included a couple small
C-class flares from regions 9770 (N09W41) and 9754 (S05W81). New
Region 9772 (S18E83) was numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
moderate levels.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
The geomagnetic field has been at quiet levels. The greater than 10
MeV proton event that began on 30/0245 UTC remains in progress,
maximum flux was 108 pfu at 31/1620 UTC.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet levels on days one and two of the forecast
period. Day three could see some isolated active conditions due to
the ejecta indicated by the Type II radio sweep mentioned in 1A.
The greater than 10 MeV proton event is expected to end on day one.
