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 224 Välja antud 2200Z kuni 11 Aug 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 10-2100Z kuni 11-2100Z Solar activity was low. Today's activity consisted of
numerous C-class flares, predominantly from Region 656 (S13E03). The
largest event of the day was a C7/Sf from 656 at 1141 UTC. Region
656 continues to grow and is nearly 1000 millionths in area. The
group continues to have a magnetic delta classification. A slow,
faint CME was seen in LASCO off the south limb yesterday, beginning
at about 10/1854 UTC in C2 imagery. The CME was associated with
surge activity and a subsequent EIT wave that was observed just
north of 656 and east of central meridian.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
to moderate. C-flares should continue and there is a good chance for
an isolated M-class event during the next three days. There is also
a slight chance for a major flare event from 656. Background levels
are expected to increase tomorrow with the return of old Region 652
(N07, Carrington = 347).
IIA. Summaarne geofüüsikaline aktiivsus 10-2100Z kuni 11-2100Z
The geomagnetic field ranged from quiet to active levels. Solar wind
data show the continuing influence of a high-speed coronal hole wind
stream. The greater than 2 MeV electron fluxes reached high levels
during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be generally unsettled with a chance for isolated active
periods for the next two days (12-13 August). Conditions are
expected to be unsettled to active on the 3rd day (14 August) with
the arrival of weak transient flow from yesterday's CME.
