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 245 Välja antud 2200Z kuni 02 SEP 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z SOLAR ACTIVITY REMAINED AT MODERATE LEVELS. REGION 8319
(N19W81) PRODUCED AN M2/SF FLARE AT 02/1707UT. THERE WERE NO
SIGNIFICANT CHANGES NOTED IN THIS STRUCTURALLY SIMPLE SPOT GROUP.
REGION 8323 (S22E16) REMAINED THE FOCUS OF INTEREST, GIVEN ITS LARGE
AREA (1430 MILLIONS) AND MAGNETIC COMPLEXITY. IT PRODUCED SEVERAL
C-CLASS SUBFLARES. ASIDE FROM A GRADUAL INCREASE IN AREA, NO
REMARKABLE CHANGES WERE OBSERVED WITHIN THIS REGION. NEW REGION 8325
(S28E47), A SMALL A-TYPE GROUP, WAS ASSIGNED TODAY.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE WITH M-CLASS FLARES POSSIBLE FROM REGIONS 8323 AND 8319.
THERE IS ALSO A FAIR CHANCE FOR A MAJOR FLARE FROM REGION 8323.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
THE GEOMAGNETIC FIELD HAS BEEN MOSTLY QUIET TO UNSETTLED. ISOLATED
ACTIVE PERIODS OCCURRED AT SOME HIGH LATITUDE STATIONS. THE GREATER
THAN 2 MEV ELECTRON FLUX WAS AT MODERATE TO HIGH LEVELS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED WITH ISOLATED ACTIVE PERIODS DURING
THE FIRST TWO DAYS. QUIET TO UNSETTLED CONDITIONS ARE EXPECTED
DURING THE FINAL DAY. THE GREATER THAN 2 MEV ELECTRON FLUX IS
EXPECTED TO REMAIN AT MODERATE TO HIGH LEVELS THROUGH THE PERIOD.
