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 240 publicerat klockan 2200Z på 27 AUG 2000IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z SOLAR ACTIVITY WAS LOW. REGION 9144 (N22W12) PRODUCED
AN C3/1N EVENT AT 26/2216Z A LARGE FILAMENT DISAPPEARED NEAR N30W36
AROUND 27/0545Z. REGION 9140 (N09W01) PRODUCED A LONG DURATION
C1/SF EVENT AT 27/1208Z. THE LARGEST EVENT WAS A C6/SF AT 27/1740Z
FROM REGION 9143 (S20E33). THIS REGION HAS SHOWN MODERATE GROWTH IN
AREA AND SPOTS SINCE YESTERDAY AND IS CURRENTLY 290 MILLIONTHS IN
WHITE LIGHT WITH 12 SPOTS. TWO NEW REGIONS WERE NUMBERED TODAY AS
REGION 9145 (S10E60) AND 9146 (S26E51).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
FOR THE FORECAST PERIOD. REGIONS 9143 AND 9144 ARE CAPABLE OF
PRODUCING AN ISOLATED M-CLASS EVENT.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 26/2100Z TO 27/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS WITH
ISOLATED ACTIVE CONDITIONS POSSIBLE.
