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 144 Välja antud 2200Z kuni 23 MAY 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT WAS A C9/2F
FROM REGION 9002 (N20W37). THIS REGION, DESPITE OBVIOUS DECAY IN
WHITE LIGHT, EMERGED AS THE MOST ACTIVE REGION ON THE VISIBLE DISK
AND PRODUCED SEVERAL SMALL FLARES DURING THE LATTER HALF OF THE
PERIOD. A SPOTLESS, UNNUMBERED REGION NEAR N07W05 PRODUCED A C5/1N
AT 23/1106Z. REGION 8996 (S20W77) CONTINUES TO BE QUITE ACTIVE, BUT
ALL FLARE ACTIVITY WAS IN THE LOW C-CLASS CATEGORY. REGION 9004
(N12W48) EXHIBITED LITTLE CHANGE IN SIZE BUT DEVELOPED INCREASED
MAGNETIC COMPLEXITY AND PRODUCED A C5/SF AT 23/1945Z.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO CONTINUE
AT LOW TO MODERATE LEVELS. REGIONS 8996, 9002 AND 9004 MAY PRODUCE
AN ISOLATED M-CLASS FLARE.
IIA. Summaarne geofüüsikaline aktiivsus 22-2100Z kuni 23-2100Z
THE GEOMAGNETIC FIELD WAS AT QUIET TO ACTIVE LEVELS. QUIET TO
UNSETTLED CONDITIONS PRECEDED A WEAK SHOCK OBSERVED AT ACE AT
23/1625Z. THE ACE SIGNATURE WAS CONSISTENT WITH A GEOEFFECTIVE
TRANSIENT THAT LIKELY ORIGINATED FROM THE C7/1N FLARE AND CME AT
20/0535Z. BZ INITIALLY WENT NORTHWARD, BUT QUICKLY TURNED SOUTHWARD
AT 23/1830Z REACHING NEAR -20NT AND RESULTING IN MINOR STORMING AT
HIGH LATITUDES. BZ RETURNED TO MORE NOMINAL CONDITIONS BY END OF
PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT UNSETTLED TO MINOR STORM LEVELS. ACTIVE TO MINOR
STORM LEVELS ARE LIKELY THROUGH DAY ONE FOLLOWING TODAY'S SHOCK
ARRIVAL. MOSTLY QUIET TO UNSETTLED CONDITIONS SHOULD PREVAIL THROUGH
DAYS 2 AND 3.
