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 225 publicerat klockan 2200Z på 12 AUG 2000IA. Analys av solfläcksgrupper och solaktivitet från 11-2100Z till 12-2100Z SOLAR ACTIVITY WAS MODERATE. AN M1 XRAY FLARE AT 0956Z,
SEEN BY SOHO EIT TO BE JUST BEYOND THE SOUTHWEST LIMB, WAS THE
LARGEST EVENT OF THE DAY. NUMEROUS C-CLASS FLARES OCCURRED, WITH
REGIONS 9114 (N10W58) AND 9125 (N25E42) CONTRIBUTING THE MAJORITY.
TWO NEW REGIONS WERE NUMBERED: 9128 (N11E61) AND 9129 (S05E72).
REGION 9125 GREW SUBSTANTIALLY DURING THE PERIOD AS IT PRODUCED
FREQUENT FLARES.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 11/2100Z TO 12/2100Z:
THE GEOMAGNETIC FIELD REMAINED AT ACTIVE TO SEVERE STORM LEVELS. THE
STRONGEST DISTURBANCES OCCURRED DURING LOCAL NIGHTTIME HOURS, AS
ENHANCED SOLAR WIND CONDITIONS CONTINUED TO DRIVE THE ACTIVITY. THE
IMF IS STILL SOUTHWARD WITH A MAGNITUDE OF 10 NT.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE AT MINOR TO MAJOR STORM LEVELS FOR THE NEXT 24 HOURS.
THE CURRENT STORM SHOULD SUBSIDE OVER TIME, YIELDING TO MORE NORMAL
CONDITIONS BY THE PERIOD'S END. EXPECT LOCAL NIGHTTIME HOURS TO BE
THE MOST AFFECTED.
