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 030 Välja antud 2200Z kuni 30 Jan 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity was very low. The day's most dramatic
event was the disappearance of a large n-s oriented filament from
the north-central disk at approximately 1000 UTC. This event was
seen as a CME further out in the corona, taking on the appearance of
a partial halo. This ejecta has an earthward component, and is
expected to pass on February 2. Otherwise, little of significance
occurred.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to continue
very low to low.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
The geomagnetic field was at mostly active levels for the past 24
hours. The solar wind radial speed rose to over 500 km/s during the
day, presumably originating from a coronal hole in the western solar
hemisphere. This feature was present last rotation, but did not
affect the magnetosphere to this degree.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to vary generally from unsettled to active levels. The
current high speed stream is likely to fuel another day of active
conditions, calming on February 1. On February 2, effects of the CME
seen near midday today are expected, bringing another episode of
active conditions, with a good chance of episodes of minor storm.
