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 220 publicerat klockan 2200Z på 08 Aug 2003IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z Solar activity was at low levels. A C2 flare occurred
at 1436Z from the east limb. Region 424 (S18W14) continues its
gradual decay and has simplified to a beta gamma magnetic
configuration. Region 425 (S09W17) was the source of a C1 flare at
1636Z.
IB. Prognos för solaktivitet
Solar activity is expected to be at
low to moderate levels. Region 424 has the potential for isolated
M-class events. Activity from the east limb is likely to continue
and possibly increase over the next three days.
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
The geomagnetic field was at active to major storm levels. Periods
of southward Bz near - 8 nT produced major and minor storm periods
early in the day. Solar wind speed increased from 600 km/s to near
800 km/s at 0600Z and has remained elevated.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at unsettled to minor storm levels. Active to minor
storm conditions are possible on day one of the period. On day two
and three of the period high speed stream effects are expected to
diminish resulting in quiet to unsettled conditions.
