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 128 publicerat klockan 2200Z på 07 MAY 2000IA. Analys av solfläcksgrupper och solaktivitet från 06-2100Z till 07-2100Z SOLAR ACTIVITY REMAINED AT A VERY LOW LEVEL. ONLY MINOR
B-CLASS ENHANCEMENTS AND SUBFLARES WERE OBSERVED. SEVERAL SMALL
REGIONS EMERGED. THE DISK REGIONS WERE ALSO SMALL AND EXHIBITED
MINOR EVOLUTION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE AT A VERY LOW
TO LOW LEVEL FOR THE NEXT THREE DAYS. CURRENT REGIONS ARE CAPABLE OF
PRODUCING ONLY ISOLATED C-CLASS EVENTS. REGIONS NEARING THE EAST
LIMB MAY RAISE C-CLASS FLARE PRODUCTION SLIGHTLY.
IIA. Sammanfattning av geofysisk aktivitet 06-2100Z till 07-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET. BRIEF UNSETTLED
CONDITIONS WERE EXPERIENCED IN THE 07/0300-0600Z PERIOD. SOLAR WIND
VELOCITY SLOWLY DECLINED TO BELOW 400 KM/S NEAR THE END OF THE
PERIOD. ENERGETIC (GT 10 MEV) PROTON FLUXES REMAINED SLIGHTLY
ELEVATED ABOVE BACKGROUND DURING THE PERIOD BUT WERE DECLINING.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD BE
PREDOMINANTLY QUIET FOR THE NEXT THREE DAYS. ISOLATED UNSETTLED
PERIODS ARE POSSIBLE. NO RECENT CORONAL MASS EJECTIONS ARE EXPECTED
TO IMPACT THE EARTH.
