Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 267 Välja antud 2200Z kuni 23 SEP 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z SOLAR ACTIVITY HAS BEEN LOW. THE LARGEST EVENT OF THE
DAY WAS AN OPTICALLY UNCORRELATED C8 FLARE AT 22/2350 UTC. EIT
IMAGERY SUGGESTS THIS EVENT WAS DUE TO ACTIVITY BEHIND THE NW LIMB.
ELSEWHERE, REGION 9169 (N11E04) REMAINS IMPRESSIVE IN SIZE AND
MAGNETIC COMPLEXITY, BUT ACTIVITY WAS LIMITED TO SEVERAL LESSER
C-CLASS SUBFAINT FLARES THROUGHOUT THE DAY, AND A DISAPPEARING
11-DEGREE SOLAR FILAMENT, THOUGH WITHOUT EVIDENCE OF ANY CME
ACTIVITY OF SIGNIFICANCE. REGIONS 9166 (S11W44) AND 9167 (N14W11)
WERE ALSO SOURCES OF C-CLASS ACTIVITY.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 9169 REMAINS A LIKELY SOURCE OF ISOLATED MAJOR
FLARE ACTIVITY, AND REGION 9166 A POSSIBLE SOURCE OF MODERATE
ACTIVITY.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 22/2100Z TO 23/2100Z:
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS THROUGHOUT THE
DAY. GREATER-THAN-2 MEV ELECTRONS AT GEOSYNCHRONOUS ORBIT WERE AT
MODERATE LEVELS DURING LOCAL DAYTIME HOURS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS THROUGH DAY ONE,
WITH AN INCREASED CHANCE OF ACTIVE LEVELS AND ISOLATED MINOR
STORMING ON DAYS TWO AND THREE, DUE TO THE EXPECTED INFLUENCE OF A
FAVORABLY POSITIONED CORONAL HOLE. MODERATE ENHANCEMENTS OF
GREATER-THAN-2 MEV ELECTRONS AT GEOSYNCHRONOUS ORBIT ARE EXPECTED
TO RECUR DURING LOCAL DAYTIME HOURS THROUGHOUT THE PERIOD.
