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 327 Välja antud 2200Z kuni 23 Nov 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z Solar activity was at low levels. The largest flare of
the period was an optically uncorrelated C4.6 x-ray event that
occurred at 23/0804 UTC. Region 198 (S18W25) produced multiple low
level C-class flares during the period. This region underwent no
significant changes in magnetic complexity or penumbral coverage
(520 millionths in areal coverage). The remaining numbered regions
were mostly quiescent throughout the period. No new regions were
numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low levels. Region 198 remains capable of producing M-class flares.
IIA. Summaarne geofüüsikaline aktiivsus 22-2100Z kuni 23-2100Z
The geomagnetic field was at quiet to active levels. Minor to major
storm conditions were experienced between 23/0300 to 0600 UTC due to
high speed solar wind resulting from the from the favorably
positioned coronal hole in the western solar hemisphere. The
greater than 2 MeV electron flux at geosychronous orbit reached high
levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to return to predominantly quiet to unsettled levels.
Active conditions are possible (mostly at high latitudes) due to the
elevated solar wind speed through day one of the forecast period as
the effects from the coronal hole subside.
