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 084 publicerat klockan 2200Z på 24 MAR 2000IA. Analys av solfläcksgrupper och solaktivitet från 23-2100Z till 24-2100Z SOLAR ACTIVITY WAS HIGH. REGION 8910 (N16W82) PRODUCED
AN X1/2B EVENT AT 24/0752UT. THE ACTIVITY INCLUDED TYPES II AND IV
SWEEPS AND A BURST OF 570 SFU AT 10 CM. TWO M-CLASS EVENTS ALSO
OCCURRED DURING THE PERIOD: AN M2/SF AT 24/1129UT FROM NEWLY
NUMBERED REGION 8928 (N21E67) AND AN OPTICALLY UNCORRELATED M2 EVENT
AT 24/1522UT. THIRTEEN SPOTTED REGIONS ARE CURRENTLY ON THE DISK.
REGIONS 8917 (N20W61), 8921 (S17E23), 8925 (S17E63), 8926 (S10W31),
AND 8927 (N17W14) WERE ALSO ACTIVE DURING THE PERIOD, ALL PRODUCING
ISOLATED OPTICAL SUBFLARES. REGION 8921 INCREASED IN SIZE BY 25
PERCENT AND NEARLY DOUBLED ITS NUMBER OF SPOTS (FROM 17 TO 26)
DURING THE PERIOD.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE WITH A CHANCE OF ISOLATED X-CLASS EVENTS.
IIA. Sammanfattning av geofysisk aktivitet 23-2100Z till 24-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET TO UNSETTLED, WITH A SINGLE
ACTIVE PERIOD OCCURRING AT 24/12-1500UT. THE SOLAR WIND SPEED
INCREASED FROM 550 TO 700 KM/S DURING THE DAY, PRESUMABLY RELATED TO
A WELL-POSITIONED CORONAL HOLE AND THE RESULTING HIGH-SPEED STREAM.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED WITH POSSIBLE ISOLATED ACTIVE
PERIODS DURING THE FIRST TWO DAYS OF THE PERIOD.
