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 079 publicerat klockan 2200Z på 20 Mar 2003IA. Analys av solfläcksgrupper och solaktivitet från 19-2100Z till 20-2100Z Solar activity was moderate. Region 314 (S13W80)
produced an M1/1f flare at 1131 UTC. The group also produced a C9/Sf
at 0231 UTC. The region appears to be in a slow decay phase as it
crosses the west limb. New Region 317 (N04E03) emerged on the disk
today as a small bipolar sunspot group.
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate for the next 24 hours due to possible additional flare
activity from Region 314. Conditions should decline to low levels
for the second and third day as Region 314 will be behind west limb.
IIA. Sammanfattning av geofysisk aktivitet 19-2100Z till 20-2100Z
The geomagnetic field was at quiet to active levels, with a minor
storm period at high latitudes from 0900-1200 UTC. An increase in
solar wind speed was observed at about 0420 UTC and may be an
indication of the passage of the flank of the CME that was
associated with the X1 flare observed at 18/1200 UTC. The greater
than 2 MeV electron fluxes were at high levels during the past 24
hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be mostly active for the next 24 hours as the current
activity persists. A gradual decline to unsettled levels is expected
for the seconds and third days.
