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 087 Välja antud 2200Z kuni 28 MAR 1997IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 27-2100Z kuni 28-2100Z SOLAR ACTIVITY WAS LOW. TODAY'S SOLE C-CLASS EVENT WAS
CLASS C1 AT 0120Z. THERE WERE NO OBSERVATIONS AVAILABLE TO PINPOINT
THE SOURCE OF THE EVENT. REGION 8026 (S24E59) IS THE ONLY SPOTTED
REGION ON THE DISK AND HAS SHOWN SLOW GROWTH OVER THE PAST 24 HOURS.
THE GROUP HAS NEW CYCLE POLARITY, WITH MAGNETICALLY NEGATIVE LEADERS
AND POSITIVE TRAILERS.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. THERE CONTINUES TO BE A FAIR CHANCE FOR ADDITIONAL,
ISOLATED C-CLASS EVENTS FROM REGION 8026.
IIA. Summaarne geofüüsikaline aktiivsus 27-2100Z kuni 28-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED FROM THE BEGINNING OF
THE PERIOD THROUGH ABOUT 28/1400Z, WHEN AN INCREASE IN ACTIVITY
BEGAN. SINCE 1400Z, ACTIVITY RANGED FROM UNSETTLED TO MINOR STORM
CONDITIONS WITH SOME ISOLATED MAJOR STORM PERIODS AT A FEW HIGH
LATITUDE SITES. SOLAR WIND DATA WERE AVAILABLE BRIEFLY DURING THE
DISTURBANCE AND INDICATED ENHANCED DENSITIES (10-15 P/CC), NOMINAL
SPEEDS (400-430 KM/S), AND A SOUTHWARD DIRECTED INTERPLANETARY
MAGNETIC FIELD OF MODERATE STRENGTH (-5 TO -10 NT). THIS SIGNATURE
SUGGESTS THAT THE ACTIVITY WAS CAUSED BY A CORONAL TRANSIENT. THE
GREATER THAN 2 MEV ELECTRON FLUXES WERE AT MODERATE TO HIGH LEVELS
TODAY.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY UNSETTLED FOR THE NEXT THREE DAYS.
