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 217 publicerat klockan 2200Z på 04 AUG 2000IA. Analys av solfläcksgrupper och solaktivitet från 03-2100Z till 04-2100Z SOLAR ACTIVITY WAS LOW. ISOLATED, OPTICALLY
UNCORRELATED LOW C-CLASS ACTIVITY OCCURRED EARLY IN THE PERIOD.
OCCASIONAL SMALL FAINT FLARES WERE OBSERVED IN REGIONS 9114 (N13E54)
AND 9115 (N17E68), BUT MAGNETIC CONFIGURATIONS IN THESE REGIONS
APPEAR RATHER SIMPLE. A LARGE, DARK FILAMENT NEAR DISK CENTER WAS
QUITE ACTIVE AND MAY SOON ERUPT. NEW REGION 9116 (S12E63) WAS
NUMBERED TODAY. REMAINING REGIONS WERE MOSTLY STABLE.
IB. Prognos för solaktivitet
SOLAR ACTIVITY WILL LIKELY REMAIN AT
LOW LEVELS. ISOLATED LOW C-CLASS ACTIVITY IS EXPECTED.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 03/2100Z TO 04/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE WITH A SINGLE MINOR STORM
PERIOD BETWEEN 04/06 - 09Z. PERIODS OF SUSTAINED SOUTHWARD BZ ARE
CAUSING THIS MINOR DISTURBANCE. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT BECAME HIGH LATE IN THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE GENERALLY QUIET TO UNSETTLED WITH ISOLATED ACTIVE
PERIODS POSSIBLE THROUGH THE NEXT THREE DAYS.
