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 045 Välja antud 2200Z kuni 14 Feb 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z Solar activity was low. Today's flare activity
consisted of a few C-class flares. The largest was a C4/1f at 0142
UTC. Most of today's flare activity was produced by 9825 (N13E01).
9825 is currently the largest, most complex region on the disk and
continued to grow slowly. Region 9821 (S12W66) continues to decay.
Two new regions rotated into view: 9829 (S07E74), a small C-type
group, and 9830 (S22E73), a small H-type group. Numerous CMEs were
observed in LASCO imagery today. Of these, a CME that was first seen
in C2 at 14/0254 UTC was associated with disk activity in EIT in the
southwest quadrant, and appears to have at least some earthward
component.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
mostly low, but there is a chance for an isolated M-class event from
9825. There is a very slight chance for a major flare from 9825.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
The geomagnetic field was mostly quiet.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled for the next 24 hours. An increase
to mostly unsettled is possible on day two due to coronal hole
effects. Day three is expected to be unsettled to slightly active
due to possible geoeffectiveness from today's CME that originated
from the southwest part of the solar disk.
