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 092 Välja antud 2200Z kuni 01 APR 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 31-2100Z kuni 01-2100Z SOLAR ACTIVITY DROPPED TO A LOW LEVEL. SEVERAL MID TO
HIGH C-CLASS EVENTS OCCURRED. REGION 8924 (N10W54) PRODUCED A C8/SF
AT 01/0349Z AND A C8/1N AT 01/0744Z. REGION 8939 (N23E44) GENERATED
A C6/SF AT 01/1151Z AND A C8/SF AT 01/1759Z. OUTSIDE OF SLIGHT
GROWTH IN REGION 8924, NO SIGNIFICANT CHANGES WERE NOTED IN THESE OR
OTHER REGIONS DURING THE PERIOD. A SMALL FILAMENT NEAR N45E20 FADED
DURING THE PERIOD.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD BE GENERALLY
MODERATE. SEVERAL REGIONS ARE CAPABLE OF PRODUCING OCCASIONAL
M-CLASS EVENTS. THERE IS A SMALL POSSIBILITY OF A MAJOR FLARE DURING
THE PERIOD.
IIA. Summaarne geofüüsikaline aktiivsus 31-2100Z kuni 01-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. ISOLATED ACTIVE PERIODS
OCCURRED. SOLAR WIND VELOCITY WAS SLOWLY INCREASING TOWARD THE END
OF THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD BE
PREDOMINANTLY QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED
ACTIVE PERIODS ARE POSSIBLE DURING THAT TIME. THERE IS A SLIGHT
POSSIBILITY OF A SOLAR PROTON EVENT DURING THE PERIOD.
