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 237 Välja antud 2200Z kuni 25 Aug 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 24-2100Z kuni 25-2100Z Solar activity was high. Region 803 (N12E67) produced
an impulsive M6/1n flare at 0440 UTC. The event was associated with
a CME off the east limb. Region 800 (N17W35) is currently the
largest on the disk but was quiet and stable. New Region 804
(N11E12) emerged on the disk today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low,
but there is a chance for an isolated M-class event from Region 800
or Region 803 during the next three days (26-28 August).
IIA. Summaarne geofüüsikaline aktiivsus 24-2100Z kuni 25-2100Z
The geomagnetic field was predominantly at active to minor storm
levels. Today's solar wind data was generally consistent with a
coronal hole stream: velocities were elevated and the magnetic field
indicated ongoing wave-like fluctuations. The speed gradually
declined from initial values around 730 km/s to day-end values
around 620 km/s. The greater than 10 MeV proton event that began at
22/2040 UTC ended today at 25/0040 UTC. The peak flux was 330 PFU at
23/1045 UTC. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be predominantly unsettled with a chance for isolated
active periods for 26 August. Conditions should be generally
unsettled for 27-28 August.
