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 25 Aug 2004IA. Analys av solfläcksgrupper och solaktivitet från 24-2100Z till 25-2100Z Solar activity was at low levels today. Region 661
(N06W86) produced the largest flare of the period, a C1 x-ray flare
that occurred at 24/2112Z. This region underwent little change
today and has begun to exit the west solar limb. Region 662
(N14W67) produced a B5 x-ray flare that had an associated Type II
radio sweep with an estimated shock speed of 800 km/s. A CME was
observed in SOHO/LASCO imagery shortly following this event which
does not appear to be Earth directed. There was some sporadic
activity seen on the southeast solar limb today that is expected to
be associated with the return of old Region 655. No new regions
were numbered today.
IB. Prognos för solaktivitet
Solar activity is expected to be at
very low to low levels.
IIA. Sammanfattning av geofysisk aktivitet 24-2100Z till 25-2100Z
The geomagnetic field was at quiet to unsettled levels today. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels throughout the period.
