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 085 Välja antud 2200Z kuni 25 MAR 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 24-2100Z kuni 25-2100Z SOLAR ACTIVITY WAS LOW. REGION 8926 (S10W45) WAS THE
MOST ACTIVE REGION DURING THE PERIOD. THIS REGION PRODUCED SEVERAL
C-CLASS EVENTS, THE LARGEST BEING A C8/SF AT 25/0947UT. REGION 8926
DIMINISHED IN SIZE SLIGHTLY DURING THE DAY BUT ALSO DEVELOPED INTO A
MORE COMPLEX BETA-GAMMA MAGNETIC CLASSIFICATION. REGIONS 8924
(N10E41), 8925 (S18E50), AND 8928 (N19E45) WERE ALSO ACTIVE DURING
THE PERIOD PRODUCING ISOLATED OPTICAL SUBFLARES. THE REST OF THE
REGIONS WERE MOSTLY STABLE AND SHOWED VERY LITTLE ACTIVITY DURING
THE DAY. AN 20 DEGREE LONG, DISAPPEARING SOLAR FILAMENT (DSF) WAS
DETECTED NEAR S54E07.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
MOSTLY LOW WITH THE POSSIBILITY OF ISOLATED M-CLASS EVENTS.
IIA. Summaarne geofüüsikaline aktiivsus 24-2100Z kuni 25-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE SOLAR WIND SPEED
BEGAN TO DECREASE DURING THE PERIOD, INDICATING THAT THE EARTH IS
MOVING OUT OF THE HIGH-SPEED CORONAL HOLE STREAM.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED.
