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 018 Välja antud 2200Z kuni 18 Jan 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 17-2100Z kuni 18-2100Z Solar activity remained at low levels. Isolated C-class
X-ray flares occurred. There were two sunspot groups of note: Region
9782 (N06W22) and Region 9786 (S26W19). Region 9782 underwent minor
changes with a small decrease in area, but continued to show a mix
of polarities within its southern leader spots. Region 9786 appeared
to be in a gradual growth phase, but was simply structured. The
remaining regions were unremarkable. New Region 9788 (N16E53) was
numbered.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
predominately low. However, there will be a small chance for an
isolated low-level M-class flare from Region 9782.
IIA. Summaarne geofüüsikaline aktiivsus 17-2100Z kuni 18-2100Z
Geomagnetic field activity was at quiet to unsettled levels. The
greater than 2 MeV electron flux at geosynchronous orbit decreased
to normal to moderate levels.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to remain at quiet to unsettled levels. However, there will
be a chance for brief active levels on 20 - 21 January due to
coronal hole effects. The greater than 2 MeV electron flux is
expected to remain at normal to moderate levels.
