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 093 Välja antud 2200Z kuni 02 APR 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z SOLAR ACTIVITY REMAINED AT A LOW LEVEL. THE LARGEST
EVENT OF THE PERIOD WAS A LONG DURATION C6/SF FROM REGION 8936
(S15E22) FROM 02/1658-1831Z. REGION 8933 (N17W43) ALSO PRODUCED
SEVERAL SUBFLARES DURING THAT TIME. DISK REGIONS WERE PREDOMINANTLY
STABLE OR DECAYING. ACTIVE SURGING WAS VISIBLE NEAR SE17 WHERE OLD
REGION 8906 IS DUE TO RETURN.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD BE LOW TO
MODERATE. CURRENT DISK REGIONS ARE CAPABLE OF PRODUCING ISOLATED
M-CLASS EVENTS. OLD REGION 8906, THAT IS BEGINNING TO APPEAR AT THE
SOUTHEAST LIMB, PRODUCED 8 M-CLASS EVENTS LAST ROTATION BUT WAS
DECAYING SLOWLY DURING ITS WESTERN HEMISPHERE TRANSIT. DEPENDING
UPON ITS RATE OF DISSOLUTION DURING THE LAST TWO WEEKS, THIS AREA
COULD ELEVATE ACTIVITY LEVELS DURING THE FORECAST PERIOD.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO SLIGHTLY ACTIVE. SOLAR WIND
VELOCITY WAS SLIGHTLY OVER NOMINAL AT 450-475 KM/S.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD
REMAIN GENERALLY UNSETTLED TO SLIGHTLY ACTIVE FOR 03-04 APR. QUIET
TO UNSETTLED CONDITIONS ARE EXPECTED ON 05 APR.
