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 336 Välja antud 2200Z kuni 02 Dec 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z Solar activity decreased to moderate levels. Region
9714 (S09W95) produced a long-duration M1 X-ray flare at 02/1500 UTC
as it crossed the west limb. A post-flare loop prominence system
followed this flare. Region 9715 (N04W37) produced isolated C-class
subflares. It remained the most impressive region on the disk, but
showed signs of gradual decay with a modest decrease in area.
However, it remained magnetically complex as a magnetic delta
configuration persisted within its interior spots. Region 9718
(S06E16) showed minor growth and produced isolated subflares, one of
which reached C-class. Some polarity mixing persisted in the trailer
portion of this region. New Region 9725 (S11W45) emerged during the
period. New Region 9726 (S15E69) rotated into view today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
mostly moderate during the period with isolated M-class flares
likely. There will also be a chance for an isolated major flare
during the period from Region 9715.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
Geomagnetic field activity was at mostly quiet levels.
IIB. Geofüüsikalise aktiivsuse ennustus
Quiet to unsettled levels are
expected. However, there will be a chance for active periods during
04 - 05 December due to coronal hole effects. There will be a slight
chance for a proton flare from Region 9715.
