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 181 publicerat klockan 2200Z på 30 Jun 2003IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z Solar activity was low. Today's activity was
characterized by occasional C-class flares. Most of these were from
Region 396 (S06W54). Region 397 (N11E40) is the largest, most
complex group on the disk but only produced two C-class flares
during the past 24 hours. New Regions 398 (N04E66) and 399 (N15E52)
were assigned today.
IB. Prognos för solaktivitet
Solar activity is expected to be
mostly low, but with a chance for an isolated M-class event sometime
during the next three days. Regions 396 and 397 are the most likely
sources for energetic flare activity.
IIA. Sammanfattning av geofysisk aktivitet 29-2100Z till 30-2100Z
The geomagnetic field ranged from unsettled to minor storm levels
during the past 24 hours. The disturbance is due to a high speed
solar wind stream associated with a well-positioned solar coronal
hole. The greater than 2 MeV electron flux was at high levels during
the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be unsettled to slightly active for the next 24 hours.
The high speed wind stream is expected to slowly subside.
Predominantly unsettled levels should prevail during the second and
third days, but there will be a chance for isolated active periods,
especially at the higher latitudes.
