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 269 publicerat klockan 2200Z på 25 SEP 2000IA. Analys av solfläcksgrupper och solaktivitet från 24-2100Z till 25-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 9166 (S12W70)
PRODUCED AN M3/1N FLARE AT 25/0053Z AND SEVERAL MINOR C-CLASS FLARES
THROUGHOUT THE PERIOD. THIS REGION HAS UNDERWENT SLOW DECAY OVER THE
PAST FEW DAYS, BUT MAINTAINS MODERATE COMPLEXITY. REGION 9169
(N11W22) PRODUCED AN M1 FLARE AT 25/0215Z WITH MODERATE CENTIMETRIC
BURSTS INCLUDING A 450SFU TENFLARE. A CME WAS ALSO OBSERVED. SOME
DECAY WAS NOTED IN THIS LARGE AND MODERATELY COMPLEX REGION WHICH
NOW MEASURES 1400 MILLIONTHS OF WHITE LIGHT AREA.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
AT LOW TO MODERATE LEVELS. REGIONS 9166 AND 9169 WILL CONTINUE TO
PRODUCE C-CLASS FLARES WITH AN ISOLATED M-CLASS FLARE LIKELY.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 24/2100Z TO 25/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. PROLONGED PERIODS OF
SOUTHWARD BZ AND ENHANCED SOLAR WIND SPEED PRODUCED OCCASIONAL
ACTIVE PERIODS. THE GREATER THAN 2 MEV ELECTRONS AT GEOSYNCHRONOUS
ORBIT WERE AT MOSTLY MODERATE TO HIGH LEVELS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY QUIET TO UNSETTLED WITH OCCASIONAL
ACTIVE PERIODS ON DAY ONE. ACTIVE TO MINOR STORM CONDITIONS ARE
POSSIBLE ON DAY TWO FROM AN EXPECTED CME PASSAGE FROM TODAY'S M1
FLARE IN REGION 9169 AT 02/0215Z. A RETURN TO QUIET TO UNSETTLED
CONDITIONS IS EXPECTED BY DAY THREE.
