Activiteitenrapport
Bij elke genoemde zonnevlam in dit rapport werd een schaalfactor toegepast door het Space Weather Prediction Center (SWPC). Vanwege de SWPC-schaalfactor worden zonnevlammen 42% kleiner gerapporteerd dan voor de wetenschappelijke data. De schaalfactor werd verwijderd uit onze gearchiveerde zonnevlamdata om de werkelijke fysieke eenheden weer te geven.
Rapport van de zonne- en geofysische activiteit van 2000 Sep 14 2200 UTC

SDF Nummer 258 gepubliceerd omstreeks 2200Z op 14 SEP 2000
IA. Analyse van de actieve zonneregio's en zonneactiviteit van 13-2100Z tot 14-2100Z
SOLAR ACTIVITY BECAME MODERATE. NEWLY NUMBERED REGION
9166 (S13E71) PRODUCED AN M1 X-RAY FLARE AT 14/0627Z. LIMB PROXIMITY
IS INHIBITING A THOROUGH ANALYSIS OF THIS REGION, BUT FREQUENT
SURGING AND POINT BRIGHTENINGS SUGGEST A MODERATELY COMPLEX REGION
ROTATING INTO VIEW. REGION 9165 (N13E13) DEVELOPED RAPIDLY IN THE
PAST 24 HOURS. FROM A SIMPLE SMALL THREE SPOT BETA CONFIGURATION
YESTERDAY, THIS REGION EVOLVED INTO A BETA-GAMMA SPOT GROUP WITH
OVER 20 SPOTS COVERING NEARLY 300 MILLIONTHS OF WHITE LIGHT AREA.
SEVERAL SMALL C-CLASS FLARES WERE OBSERVED IN THIS REGION. SLIGHT
GROWTH WAS ALSO NOTED IN REGIONS 9156 (S26W53), AND 9162 (S32W63).
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. M-CLASS ACTIVITY IS BECOMING MORE LIKELY WITH THE
EMERGENCE OF REGION 9165, AND NEW REGION 9166.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 13/2100Z TO 14/2100Z:
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED. THE >10 MEV PROTON
EVENT THAT BEGAN AT 12/1555Z IS STILL IN PROGRESS. A MAXIMUM VALUE
OF 321 PFU OCCURRED AT 13/0340Z. THE EVENT HAS BEEN IN SLOW DECAY
SINCE THE MAXIMUM AND IS CURRENTLY AT 18 PFU. THE PCA THAT BEGAN
NEAR 12/1830Z, ENDED AT 14/1532Z.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO SOON EXPERIENCE MINOR TO MAJOR STORM CONDITIONS. A CME
ASSOCIATED WITH THE 12 SEP, M1/2N FLARE WILL LIKELY IMPACT EARLY ON
DAY ONE. STORM CONDITIONS SHOULD PERSIST FOR MOST OF DAY ONE AND
RETURN TO UNSETTLED CONDITIONS BY DAYS TWO AND THREE. THE >10 MEV
PROTON EVENT SHOULD END ON DAY ONE, ALTHOUGH AN ENHANCEMENT IS POSSIBLE
WITH THE PASSAGE OF THE EXPECTED CME.

Voorspeld 15 SEP-17 SEP 155/160/170
90 dagen gemiddelde 14 SEP 177
V. Geomagnetische A index
OBSERVED AFR/AP 13 SEP 008/010
ESTIMATED AFR/AP 14 SEP 010/013
PREDICTED AFR/AP 15 SEP-17 SEP 050/045-015/012-008/012
