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.

Количество SD 016 на уровне 2200Z 16 Jan 2012
IA. Анализ активных солнечных регионов и активности от 15 - 2100Z до 16 - 2100Z
Solar activity was at low levels. Region 1402 (N28E53)
produced a long duration event (LDE) early on 16 January. The LDE
began at 16/0236Z, reached a maximum at 16/0444Z and ended at
16/0646Z. A partial-halo CME was seen lifting off the ENE limb,
first observed in LASCO C2 imagery at 16/0342Z with an initial
radial velocity of about 793 km/s. Model output indicated the
potential for a glancing blow from the CME beginning late on 19
January. Other activity included a C5/Sf flare from Region 1401
(N17E51) at 16/1038Z. Both Region 1401 and 1402 doubled in area as
they continued to rotate onto the visible disk. New Region 1404
(N12W29) emerged on the disk as a D-type group, while new Region
1405 (N13E65) rotated onto the disk as an H-type group.
IB. Прогноз солнечной активности
Solar activity is expected to be at
low levels with a chance for M-class activity for the next three
days (17 - 19 January), particularly from the east limb complex of
spots.
IIA. Обзор геофизической активности от 15 - 2100Z до 16 - 2100Z
The geomagnetic field was at predominately quiet to unsettled levels
with isolated intervals of active to minor storm conditions at high
latitudes. Solar wind velocities, as measured at the ACE
spacecraft, ranged between 350 - 400 km/s through 16/0900Z. At that
point, a gradual increase in wind speeds to about 500 km/s was
observed with a corresponding southward dip to near -10 nT in the Bz
component of the interplanetary magnetic field.
IIB. Прогноз геофизической активности
The geomagnetic field is
expected to be at mostly quiet to unsettled levels, with isolated
active periods, on day one (17 January). Day two (18 January)
should see a return to mostly quiet levels. By day three (19
January), the field is expected to be at mostly quiet levels through
a majority of the day. Late on 19 January, an increase to quiet to
unsettled levels, with isolated active periods, are expected due to
anticipated effects from a glancing blow from the 16 January CME.
