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 100 Välja antud 2200Z kuni 10 Apr 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 09-2100Z kuni 10-2100Z Solar activity was at high levels. An M8.2/1N flare
occurred at 10/1231 UTC from Region 9893(N19W14) characterized by
parallel ribbons and multiple eruptive centers. Associated with
this flare was a Type II radio burst (702 km/s) and a partial halo
CME observed from SOHO/LASCO imagery. Region 9893 has begun to
decay and has simplified to a beta-gamma magnetic configuration.
Region 9899 (N18E22) has increased in magnetic complexity to a
beta-gamma spot and produced an M1.6/1n flare at 10/1907 UTC.
Region 9901(N20W02) has shown growth in spot count and magnetic
complexity. Region 9904 (S16W21) has developed a small delta
configuration in the leader spot. Region 9905 (S17E04) was numbered
today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate. Region 9893 is in decay phase but still has the potential
for a major flare. Region 9899 and Region 9901 are in a growth
phase and could produce M-class events.
IIA. Summaarne geofüüsikaline aktiivsus 09-2100Z kuni 10-2100Z
The geomagnetic field was at quiet levels for most of the day with
one period of unsettled conditions from 15-18Z. The lingering
effects of the high speed stream appear to be ending. Greater than
2 MeV electrons have returned to near background levels after three
days of enhancement.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to active. There is a chance of increased
geomagnetic activity late on day two due to a CME shock passage. On
day three of the forecast period another CME shock is expected (from
the M8/1N flare on 10/1231 UTC) and geomagnetic activity is expected
to reach unsettled to active conditions. There is a slight chance
of isolated minor storm levels especially at high latitudes.
