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 021 Välja antud 2200Z kuni 21 Jan 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 20-2100Z kuni 21-2100Z Solar activity has been high during the past 24 hours
due to an M7/2b flare at 20/2120Z from Region 9313 (S07E28). The
event was accompanied by a type II radio sweep and was also
associated with a CME. Yesterday's M1 flare (at 20/1847Z) was also
associated with a CME. The first of these two CMEs appeared to move
slowly and showed a full-halo signature, whereas the second CME was
fast and confined to a region off the East limb of the Sun. The
remainder of today's activity consisted of a couple low-level
C-class events. Three new sunspot regions were assigned today:
Region 9319 (S20W43), Region 9320 (S25E01) and Region 9321 (S05E69).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. Region 9313 is the main threat for M-class level
events.
IIA. Summaarne geofüüsikaline aktiivsus 20-2100Z kuni 21-2100Z
The geomagnetic field ranged from quiet to minor storm levels. Most
of today's activity was quiet to unsettled, Activity was enhanced
between 0900-1800Z, with mostly active levels, and a minor storm
period from 0900-1200Z. Solar wind data indicated two sector
boundary crossings during the past 24 hours, which may be related to
the geomagnetic activity.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly unsettled during the next 24 hours. An
increase to unsettled to active levels is expected for the 2nd and
3rd days, in response to the full-halo CME of 20 January.
