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 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 20-2100Z kuni 21-2100Z Solar activity decreased to low levels today. Flare
activity was sparse, although Region 543 (S16W21) produced a C2/Sf
that occurred at 21/0036Z. A slight decay was seen in this region
since yesterday. Region 540 (S14W35) lost the delta structure in
the trailing position of spot cluster overnight. Region 542
(N10W16) underwent no significant changes. Region 544 (N08W04)
decayed slightly in penumbral coverage during the period. All
spotted regions retain their beta-gamma magnetic features. A 28
degree disappearing solar filament was observed on SXI and SOHO/EIT
imagery near 21/1200Z. LASCO imagery is inconclusive at this time
but initial C2 data indicates there is a resulting CME from this
activity. No new regions were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low to moderate levels.
IIA. Summaarne geofüüsikaline aktiivsus 20-2100Z kuni 21-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to range from quiet to minor storm levels. Isolated
periods of major storm conditions are possible with the onset of the
anticipated shock passage, due early on 22 Jan; resulting from the
long duration C-flare that occurred late on 19 Jan. Unsettled to
active levels are expected on 23 Jan. Predominantly quiet to
unsettled conditions should return by 24 Jan.
