Отчет о солнечной активности
Любая солнечная вспышка, упомянутая в этом расчете, имеет масштабирующий коэффициент, применяемый Центром прогнозирования космической погоды (SWPC). Из-за него солнечные вспышки здесь на 42% слабее, чем в научных данных. Из наших архивов этот коэффициент был удален, чтобы показать реальные величины вспышек.
Отчет о солнечно-геофизической активности 2000 Sep 14 2200 UTC

Количество SD 258 на уровне 2200Z 14 SEP 2000
IA. Анализ активных солнечных регионов и активности от 13 - 2100Z до 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. Прогноз солнечной активности
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. Прогноз геофизической активности
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.
