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.

IA. Анализ активных солнечных регионов и активности от 06 - 2100Z до 07 - 2100Z
Solar activity has been high. Region 696 (N08W22)
produced numerous C-class flares, and at 1606 UTC a long duration
X2.0 flare, accompanied by a Type II radio sweep (673 km/s), a Type
IV radio sweep, and a 4600 sfu Tenflare. A CME may have occurred in
association with this flare, although LASCO imagery was not
available. Region 696 decayed significantly to an area of 650
millionths in white light. The region maintains its complex
beta-gamma-delta magnetic configuration. No new regions were
numbered today.
IB. Прогноз солнечной активности
Solar activity is expected to be
moderate to high. Although it has decayed in size, Region 696 is
expected to produce M-class and isolated X-class flares.
IIA. Обзор геофизической активности от 06 - 2100Z до 07 - 2100Z
The geomagnetic field has been at quiet to major storm levels. A
shock arrived at ACE at 1555 UTC which caused subsequent major
storming in Earth's magnetic field beginning at 1608 UTC. Another
shock passage was observed at ACE at 1755 UTC that resulted in a
41nT sudden impulse at 1831 UTC followed by minor storming. These
shock passages are most likely from the CMEs associated with flare
activity on 3 and 4 November. The greater than 10 MeV proton flux
crossed 10 pfu at 1910 UTC and ended the period at 72 pfu. The
greater than 100 MeV proton flux was elevated but did not cross the
1 pfu threshold. Energetic proton activity was most likely
associated with the X2 flare.
IIB. Прогноз геофизической активности
The geomagnetic field is
expected to be at unsettled to major storm levels. A shock passage
from the CME associated with the M2/M5 flares from 5 November is
expected to arrive early on 8 November, and a shock passage from the
CME associated with the M9 flare from 6 November is expected to
arrive on 9 November. Today's X2 flare very likely produced a CME
that could arrive late on 9 November. These anticipated shock
passages, along with the elevation in solar wind speed due to a
geoeffective coronal hole, should keep geomagnetic activity at
unsettled to minor storm levels all three days, with isolated major
storming possible on 8-9 November. The greater than 10 MeV proton
flux at GOES is expected to stay above the 10 pfu threshold through
8 November, and will likely cross the 100 pfu threshold early on 8
November.
