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 294 publicerat klockan 2200Z på 21 Oct 2010IA. Analys av solfläcksgrupper och solaktivitet från 20-2100Z till 21-2100Z Solar activity was very low. Todays activity consisted
of occasional, low-level B-class flares. Most of these were either
from Region 1112 (S20, behind west limb) or Region 1117 (N23E48),
although at least one event appeared to originate from a new group
just behind the East limb (around N25). Regions 1113 (N16W31) and
1115 (S29W13) were quiet and stable.
IB. Prognos för solaktivitet
Solar activity is expected to be very
low, although there is a slight chance for an isolated C-class event
during the next three days (22-24 October).
IIA. Sammanfattning av geofysisk aktivitet 20-2100Z till 21-2100Z
The geomagnetic field was quiet during the past 24 hours.
IIB. Prognos för geofysisk aktivitet
The geomagnetic field is
expected to be generally quiet for the first day (22 October) and
about halfway through the second day (23 October). Sometime around
mid-day on 23 October and continuing through the third day (24
October), an increase to unsettled levels with a chance for active
periods is expected. There is also a chance for isolated storm
periods at some locations during this interval. The increase is
forecast because of expected effects from a high speed solar wind
stream from a favorably positioned coronal hole.
