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 293 publicerat klockan 2200Z på 20 Oct 2010IA. Analys av solfläcksgrupper och solaktivitet från 19-2100Z till 20-2100Z Solar activity was at low levels. Region 1112 (S20W84)
produced the lone event of the period, a C1.5/Sf at 20/1150Z. The
remaining regions were quiet and unchanged.
IB. Prognos för solaktivitet
Solar activity is expected to be
predominately very low all three days of the forecast period (21 -
23 October). A chance for an isolated C-class event exists on day
one (21 October) from departing Region 1112, decaying to a slight
chance of C-class activity on days two and three (22 - 23 October).
IIA. Sammanfattning av geofysisk aktivitet 19-2100Z till 20-2100Z
The geomagnetic field was quiet. Solar wind velocities remained
steady during the period, varying between 420 - 460 km/s while the
Bz component of the interplanetary magnetic field remained
predominately north.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be at quiet to unsettled levels, with isolated active
periods on day one (21 October). A small, recurrent coronal hole
high speed stream (CH HSS) is expected to rotate into a geoeffective
position on 21 October. By day two (22 October), field conditions
are expected to be mostly quiet. Late on day three (23 October), a
large, recurrent CH HSS is expected to become geoeffective,
resulting in quiet to active conditions.
