Solaktivitetsrapport
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.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 041 publicerat klockan 2200Z på 10 FEB 1997IA. Analys av solfläcksgrupper och solaktivitet från 09-2100Z till 10-2100Z SOLAR ACTIVITY REMAINED VERY LOW. THE DISK BECAME
SPOTLESS.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW FOR THE NEXT THREE DAYS.
IIA. Sammanfattning av geofysisk aktivitet 09-2100Z till 10-2100Z
THE GEOMAGNETIC FIELD WAS GENERALLY UNSETTLED TO ACTIVE. ISOLATED
PERIODS OF MINOR STORMING OCCURRED AT MID LATITUDES AND SOME HIGH
LATITUDE SITES EXPERIENCED OCCASIONAL MAJOR STORM CONDITIONS. SOLAR
WIND DATA INDICATED A MAGNETIC CLOUD PASSED THE L1 POSITION NEAR
09/1230Z. THE BZ COMPONENT OF THE FIELD WAS OBSERVED ON 10 FEB TO SLOWLY CROSS
FROM 6 NT SOUTHWARD TO ZERO NEAR 10/1845Z IMPLYING THE MIDDLE OF THE
CLOUD WAS PASSING THE EARTH AROUND THAT TIME. ENERGETIC ELECTRON
FLUXES AT GEOSYNCHRONOUS ORBIT REACHED HIGH LEVELS NEAR 10/0945Z AND
ROSE QUICKLY TO VERY HIGH LEVELS AT ABOUT 10/1400Z.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
FORECAST TO BE PREDOMINANTLY UNSETTLED TO ACTIVE FOR 11 FEB. BRIEF
MINOR AND MAJOR STORM PERIODS ARE POSSIBLE DURING THAT TIME AS THE
MAGNETIC CLOULD COMPLETES ITS TRANSIT PAST THE EARTH. UNSETTLED TO
ACTIVE LEVELS ARE FORECAST FOR 12 FEB BECOMING MOSTLY QUIET BY 13
FEB.
