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 174 publicerat klockan 2200Z på 22 JUN 2000IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z SOLAR ACTIVITY HAS BEEN LOW. REGION 9042 (N23W54)
PRODUCED MOST OF TODAY'S C-CLASS EVENTS, INCLUDES THE LARGEST, A
C5/SF AT 0023Z. REGIONS 9040 (N18W73) AND 9046 (N20W21) ALSO
EXHIBITED SUBFLARE LEVEL BRIGHTENINGS DURING THE EVENT REGION 9042
HAS CONTINUED TO DECAY, ESPECIALLY IN THE TRAILER PORTION OF THE
GROUP. REGION 9046 (N20W21) ALSO CONTRIBUTED A FEW C-CLASS EVENTS
AND HAS SHOWN A SLIGHT DECREASE IN AREA. NEW REGION 9057 (N14E72)
ROTATED INTO VIEW TODAY AS A SIMPLE H-TYPE REGION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE
MOSTLY LOW, BUT THERE IS A CHANCE FOR AN ISOLATED M-CLASS EVENT
SOMETIME DURING THE NEXT THREE DAYS. REGIONS 9042 AND 9046 ARE
CONSIDERED TO BE THE MOST LIKELY SOURCES FOR M-CLASS FLARES.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE. QUIET TO UNSETTLED
LEVELS PREDOMINATED FOR MOST OF THE DAY, BUT THERE WAS ONE ACTIVE
PERIOD FROM 0000-0300Z. REAL-TIME SOLAR WIND OBSERVATIONS FROM THE
ACE SPACECRAFT INDICATED A SOLAR SECTOR BOUNDARY CROSSING FROM AN
'AWAY' (POSITIVE) CONFIGURATION TO A 'TOWARDS' (NEGATIVE)
CONFIGURATION BETWEEN 0100-1200Z.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOST UNSETTLED TOMORROW, BUT GRADUAL INCREASE TO
UNSETTLED TO ACTIVE IS ANTICIPATED LATE TOMORROW OR BY THE SECOND
DAY. THE INCREASE IS EXPECTED AS A RESPONSE TO THE INFLUENCE OF A
RECURRENT CORONAL HOLE.
