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 266 publicerat klockan 2200Z på 22 SEP 2000IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z SOLAR ACTIVITY HAS BEEN LOW. MOST ACTIVITY OCCURRED IN
REGION 9169 (N10E13), WHICH PRODUCED SEVERAL C-CLASS FLARES
THROUGHOUT THE DAY, THE LARGEST BEING A C5/SF IN PROGRESS AT THE END
OF THE PERIOD, 22/2100 UTC. THIS REGION REMAINS THE LARGEST AND
MOST IMPRESSIVE ON THE DISK, EXHIBITING AN INCREASED NUMBER OF SPOTS
WITH SLIGHTLY REDUCED AREAL EXTENT SINCE YESTERDAY, AND RETAINING
A BETA-DELTA-GAMMA MAGNETIC CONFIGURATION. REGION 9166 (S12W30)
ALSO PRODUCED SOME C-CLASS ACTIVITY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINANTLY LOW TO MODERATE FOR THE NEXT THREE DAYS. REGION 9169
REMAINS A LIKELY SOURCE OF ISOLATED MAJOR FLARE ACTIVITY.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 21/2100Z TO 22/2100Z:
THE GEOMAGNETIC FILED HAS BEEN PREDOMINANTLY QUIET THROUGHOUT THE
DAY. ISOLATED UNSETTLED PERIODS WERE OBSERVED AT HIGHER LATITUDES.
GREATER-THAN-2 MEV ELECTRONS AT GEOSYNCHRONOUS ORBIT WERE AT
MODERATE LEVELS DURING LOCAL DAYTIME HOURS.
IIB. Prognos för geofysisk aktivitet
BARRING AN EARTH-DIRECTED CME
FROM REGION 9169, THE GEOMAGNETIC FIELD IS EXPECTED TO PERSIST AT
QUIET TO UNSETTLED LEVELS THROUGH THE FIRST TWO DAYS, WITH AN
INCREASED CHANCE OF ACTIVE LEVELS BY DAY THREE DUE TO THE INFLUENCE
OF A FAVORABLY POSITIONED CORONAL HOLE.
