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 293 Välja antud 2200Z kuni 20 Oct 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 19-2100Z kuni 20-2100Z Solar activity was moderate. Region 160 (S21W26)
produced two M-class events, the largest an M1.8/1b at 20/1428 UTC
with an associated Type II radio sweep (657 km/s). Region 160 has
increased in magnetic complexity to a beta-gamma configuration due
to mixing in the leading spots. Region 162 (N26E46) continues to
grow in area coverage and spot count. This region has produced two
M-class events, the largest an M1.8/Sf at 20/0045 UTC. Region 162
maintains its beta-gamma magnetic configuration and polarity mixing
has been observed in the leading edge of the trailing spots. Region
158 (S07W32) produced only minor flares and has simplified to a beta
magnetic configuration. Two new regions were numbered today:
Region 164 (N11E54) and Region 165 (N20E71).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. Region 160 and Region 162 have M-class potential.
IIA. Summaarne geofüüsikaline aktiivsus 19-2100Z kuni 20-2100Z
The geomagnetic field was at quiet to unsettled levels. The high
speed stream continues but effects are minimal due to a consistently
northward Bz.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled. There is a chance of isolated
active to minor storm conditions on day two and day three due to
effects from the M-class activity mentioned above.
