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 089 Välja antud 2200Z kuni 30 MAR 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z SOLAR ACTIVITY WAS LOW. TODAY'S LARGEST X-RAY EVENT WAS
A C1 AT 1952Z; THERE WERE NO CORRESPONDING OPTICAL SIGNATURES. A
SIGNIFICANT PORTION OF THE NORTHERN POLAR CROWN FILAMENT (NEAR
N31W43) DISAPPEARED BETWEEN 1235-1503Z. REGION 8185 (S25W39) IS THE
DOMINANT REGION ON THE DISK IN TERMS OF SUNSPOT AREA AND MAGNETIC
COMPLEXITY. NONETHELESS THE REGION WAS QUIET AND STABLE DURING THE
PAST 24 HOURS.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW,
BUT THERE IS A CONTINUED POSSIBILITY FOR AN ISOLATED M-CLASS EVENT
FROM REGION 8185.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. SOME
MINOR SUBSTORM ACTIVITY WAS NOTED AT HIGH LATITUDES BETWEEN
1400-1700Z. THE GREATER THAN 2 MEV ELECTRONS WERE AT HIGH FLUX
LEVELS DURING THE PAST 24 HOURS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED WITH OCCASIONAL ACTIVE PERIODS OVER THE
NEXT TWO DAYS. THE PROBABILITY FOR ENHANCED ACTIVITY IS SOMEWHAT
HIGHER THAN USUAL DUE TO THE LONG DURATION M2 ON THE 27TH AND THE
FILAMENT ERUPTION ON THE 29TH. THERE IS EVIDENCE FROM LASCO THAT THE
FILAMENT ERUPTION WAS ASSOCIATED WITH A CORONAL MASS EJECTION.
GEOMAGNETIC CONDITIONS ARE EXPECTED TO DECLINE TO QUIET TO UNSETTLED
ON THE THIRD DAY.
