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 142 Välja antud 2200Z kuni 22 May 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 21-2100Z kuni 22-2100Z Solar activity remained at very low levels. Region 766
(N15E62) has fully rotated onto the visible disk and it appears to
be a DAO beta spot group. Region 767 (S07E67) has also fully
rotated onto the visible disk and it appears to be a DAO beta spot
group. Both of these regions were relatively quiet during the
period. No new regions were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low levels.
IIA. Summaarne geofüüsikaline aktiivsus 21-2100Z kuni 22-2100Z
The geomagnetic field was at predominantly quiet to active levels. A
brief period of minor storming was observed at the Boulder
magnetometer between 22/0000 and 0300Z. Several hours of a
sustained southward Bz preceded the storming conditions. 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. Isolated
active conditions may be possible with periods of sustained
southward Bz throughout the interval at the higher latitudes.
