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 227 Välja antud 2200Z kuni 14 Aug 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z Solar activity remained at high levels today. Region
656 (S13W35) produced multiple M-class flares today. There were two
major flares reported during the period, an M7/2n event at 14/0544Z
and an M5/2n occurring at 14/1343Z. SOHO/LASCO imagery depicts
several CMEs that all appear to have a solar westward component.
This region continues to exhibit a beta-gamma-delta magnetic
structure with some decay in the sunspot area seen over the period.
The remaining active regions were quiescent throughout the period.
No new regions were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
moderate to high levels. Region 656 remains capable of producing
further major flare activity.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
The geomagnetic field was at quiet to unsettled levels. A weak shock
passed the ACE spacecraft at approximately 13/2200Z that is presumed
to be from the faint halo CME that was observed late on 10 August.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels throughout
the period. Isolated active conditions are possible late on 16 and
through 17 August due to glancing blows from the CME activity seen
today.
