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 356 Välja antud 2200Z kuni 22 Dec 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 21-2100Z kuni 22-2100Z Solar activity was at low levels. Region 9749 (S08E43)
produced a C3/Sf flare at 21/2152 UTC. Three additional optically
uncorrelated C-class flares were observed during the period. Region
9742 (N10W16) continues to be the largest and most magnetically
complex region on the disk. This region was stable and appears to
have slightly decreased in areal coverage during the period. A
15-degree filament near S19E26 disappeared sometime between 22/0108
UTC and 22/0225 UTC. A second, smaller, filament disappeared near
N15E49 between 22/1636 UTC and 22/1653 UTC. New Regions 9752
(S14W19) and 9753 (S20E67) were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low to moderate levels. Region 9742 remains capable of producing
M-class flares and there is a chance for an isolated major flare
from this region.
IIA. Summaarne geofüüsikaline aktiivsus 21-2100Z kuni 22-2100Z
The geomagnetic field was at quiet to unsettled levels.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled levels. High latitudes may
experience isolated active conditions on days two and three of the
period as a favorably positioned coronal hole is expected to become
geoeffective.
