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 023 Välja antud 2200Z kuni 23 Jan 2001IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z Solar activity was low. Region 9311 (N06W62) produced
today's largest flare, a C4/Sf at 2044Z. This group continues to
show slow growth and has a simple beta magnetic configuration.
Region 9313 (S06E01) continues to show some magnetic complexity but
appears to be decaying slowly. Three new sunspot groups were
assigned today: Region 9322 (S23E00), Region 9323 (S29E03) and
Region 9324 (N10E42). All of these groups were small, simple,
bipolar regions.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
mostly low, but there is a chance for an isolated M-class event
during the next three days. Regions 9313 and 9311 are the most
likely sources for enhanced solar activity.
IIA. Summaarne geofüüsikaline aktiivsus 22-2100Z kuni 23-2100Z
The geomagnetic field was at quiet to active levels during the past
24 hours. The field was initially quiet. However, an interplanetary
shock was observed at the ACE spacecraft at 1008Z and was followed
by a sudden impulse at Earth at 1047Z. Solar wind behind the shock
showed sheath-like characteristics, with Bz oscillating from
negative to positive. Bz did appear to be trending toward more
strongly negative values near forecast issue time (about -10 nT).
The geomagnetic field responded by becoming unsettled to active.
The greater than 10 MeV protons remain enhanced (at about 2 pfu)
but did not increase with the shock passage.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly active during the next 12 to 24 hours, with a
chance for isolated storm periods as the current disturbance
continues. A decrease to unsettled to slightly active levels is
expected for the second and third days.
