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 274 publicerat klockan 2200Z på 30 SEP 2000IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z SOLAR ACTIVITY WAS MODERATE. IT IS BELIEVED REGION
9178 (S23E40) PRODUCED A SLOW RISE, LONG DURATION M1 X-RAY EVENT
THAT REACHED MAXIMUM AT 30/1827Z. A SECOND M1 X-RAY EVENT OCCURRED
AT 30/2016Z WITH NO OPTICAL CORRELATION. REGIONS 9173 (S11W02) AND
9178 PRODUCED SEVERAL C-CLASS EVENTS DURING THE PERIOD. GROWTH WAS
OBSERVED IN REGIONS 9173, 9176 (S09E31), AND 9178. REGION 9176 NOW
HAS A BETA-GAMMA MAGNETIC CONFIGURATION WITH APPROXIMATELY 24 SPOTS.
NEW REGION 9179 (N34E07) WAS NUMBERED TODAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 9173, 9176 (S09E31), AND 9178 EACH HAVE THE
POTENTIAL TO PRODUCE AN M-CLASS EVENT.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 29/2100Z TO 30/2100Z:
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MAJOR STORM LEVELS. A
DISTURBANCE OF UNKNOWN ORIGIN BEGAN AROUND 30/0400Z. MAJOR STORM
LEVELS WERE OBSERVED IN THE HIGH LATITUDES FROM APPROXIMATELY
30/0800 - 1200Z. THE MID LATITUDES OBSERVED MINOR STORM CONDITIONS
DURING THE SAME PERIOD. THE GEOMAGNETIC FIELD RETURN TO UNSETTLED
CONDITIONS AT THE END OF THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO RANGE FROM QUIET TO ACTIVE DURING THE FIRST DAY,
BECOMING MORE QUIET TO UNSETTLED THE REST OF THE PERIOD.
