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 298 publicerat klockan 2200Z på 24 Oct 2012IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z Solar activity has been low. Region 1598 (S12E29) has
produced numerous C-class events throughout the period, and remains
the most magnetically complex region on the disk. Although slight
decay was noted in Region 1598s trailer spots, it still maintains a
Delta magnetic configuration. Region 1596 (N08W08) is moderately
sized with some magnetic complexity, but did not produce any flares
during the period. The other regions either remained stable or were
decaying.
IB. Prognos för solaktivitet
Solar activity is expected to be
moderate to high with occasional M-class events, and a slight chance
for an isolated X-class event for the next three days (25 - 27 Oct)
with Region 1598 the most likely source.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
The geomagnetic field was quiet for the past 24 hours. Solar wind
speed, as measured at the ACE spacecraft, decreased slowly
throughout the period from around 370 km/s to around 340 km/s. The
Bz component of the interplanetary magnetic field ranged from +/- 2
nT. The greater than 2 MeV electron flux at geosynchronous orbit
reached high levels during the period.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be quiet for the next three days (25 - 27 Oct).
