Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 300 Välja antud 2200Z kuni 27 Oct 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 26-2100Z kuni 27-2100Z Solar activity was low during the past 24 hours.
Today's activity consisted of occasional low-level C-class flares,
all from Region 162 (N26W43). Region 162 showed emergence of new
flux in the northwest portion of the trailing spots, leading to the
formation of a new delta configuration. A large, southern polar
crown filament lifted of the disk around 0900 UTC on the 27th and
was observed as a small CME in the LASCO C3 field of view.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate during the next three days. There is a fair chance for
an isolated M-class event from Region 162. The newly formed delta
configuration also poses a slight threat for major flare activity.
IIA. Summaarne geofüüsikaline aktiivsus 26-2100Z kuni 27-2100Z
The geomagnetic field was unsettled to active during the past 24
hours. The magnetosphere continues to be under the influence of a
high speed solar wind stream with persistently negative orientation
of the interplanetary magnetic field component Bz. The greater the 2
MeV electron fluxes reached high levels during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be unsettled to active during the next 12-24 hours due
to persistent effects of the high speed solar wind stream.
Predominantly unsettled levels are expected for the second and third
days.
