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 290 Välja antud 2200Z kuni 17 Oct 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 16-2100Z kuni 17-2100Z Solar activity was very low. Today's largest flares
were a B9 at 0701 UTC from newly numbered Region 482 (N16E62), and a
long-duration B8 at 0932 UTC from behind east limb at about N03.
Newly numbered Region 481 (S08W17) emerged on the disk today. Solar
imagery suggests that there are additional active regions close to
east limb which will be rotating into view soon.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low to low. There is a fair chance for an isolated C-class flare
sometime during the next three days.
IIA. Summaarne geofüüsikaline aktiivsus 16-2100Z kuni 17-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The
earth continues to be under the influence of a high-speed solar wind
stream. The stream continues to decline slowly as the initial speeds
around 560 km/s decreased down to about 520 km/s by the end of the
period. The interplanetary magnetic field showed regular oscillations
and had a weakly negative Bz component on average during the past 24
hours. The greater than 2 MeV electron fluxes were at high levels
during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be unsettled to active for the next 24 hours. Unsettled
levels are expected to prevail for the second and third days.
