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 104 publicerat klockan 2200Z på 13 APR 2000IA. Analys av solfläcksgrupper och solaktivitet från 12-2100Z till 13-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. REGION 8948
(S15W49) SHOWED GRADUAL SIMPLIFICATION OF ITS MAGNETIC STRUCTURE,
BUT MAINTAINED A BETA-GAMMA CLASSIFICATION. IT PRODUCED A C-CLASS
SUBFLARE EARLY IN THE PERIOD. SLIGHT GROWTH WAS REPORTED IN REGION
8959 (S17E14). THE REMAINING REGIONS WERE STABLE INCLUDING NEWLY
NUMBERED REGIONS 8960 (N19W15), 8961 (S25E07), 8962 (N21E76), AND
8963 (N15E74).
IB. Prognos för solaktivitet
ACTIVITY IS EXPECTED TO BE AT LOW TO
MODERATE LEVELS. THERE IS A FAIR CHANCE FOR AN ISOLATED M-CLASS
FLARE FROM REGION 8948.
IIA. Sammanfattning av geofysisk aktivitet 12-2100Z till 13-2100Z
GEOMAGNETIC FIELD ACTIVITY RANGED FROM QUIET TO UNSETTLED LEVELS. THE
GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REMAINED AT
MODERATE TO HIGH LEVELS.
IIB. Prognos för geofysisk aktivitet
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS DURING MOST OF THE
PERIOD. HOWEVER, BRIEF ACTIVE PERIODS ARE POSSIBLE ON 15 APRIL DUE
TO A SMALL, FAVORABLY POSITIONED CORONAL HOLE. THE GREATER THAN 2
MEV ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT IS EXPECTED TO DECREASE TO
NORMAL TO MODERATE LEVELS EARLY IN THE PERIOD.
