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 238 publicerat klockan 2200Z på 26 Aug 2006IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z Solar activity was low. Region 905 (S08E05) produced a
C2 flare at 26/2007Z. New opposite flux emerged around the leading
sunspot resulting in increased flare potential in this reverse
polarity group.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low to low. There is a chance for further C-class flares from Region
905.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
The geomagnetic field was quiet. Solar wind speed ended the period
near 330 km/s. The greater than 2 MeV electron flux at
geosynchronous orbit was at high levels again today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to range from quiet to minor storm conditions over the next
three days. A recurrent coronal hole high speed stream is expected
to rotate into a geoeffective position on 27 and 28 August, and
produce unsettled to active levels with isolated minor storm
periods. Quiet to unsettled conditions, with isolated active periods
are expected on 29 August. The x-ray signature of the C2 flare late
today indicates a possible CME. The flare location was near center
disk so a geomagnetic disturbance is possible on 29 August. The
forecast will be updated as appropriate to reflect this change.
