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 031 Välja antud 2200Z kuni 31 Jan 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 30-2100Z kuni 31-2100Z Solar activity was low. There were three C-class flares
during the past 24 hours, the largest of which was a C2 at 0606 UTC.
Solar X-ray images clearly show that the source for all of these
events was a new active region just behind the East limb at about
S15. A 17 degree filament near S11E02 disappeared between 0223 UTC
and 1137 UTC. All of the active regions on the disk were stable and
quiet.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
for the next three days.
IIA. Summaarne geofüüsikaline aktiivsus 30-2100Z kuni 31-2100Z
The geomagnetic field ranged from quiet to active levels with a minor
storm period at high latitudes. Solar wind data indicate the
presence of a high speed solar wind stream associated with a coronal
hole. The greater than 2 MeV electron fluxes reached high levels
during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly unsettled tomorrow, but there is a chance
for some active periods. Effects from the halo CME of 30 January
are expected to arrive some time around midday tomorrow and should
increase levels to active through the second day. Conditions should
decline to unsettled to slightly active on the third day.
