Отчет о солнечной активности
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.

Совместный отчет USAF/NOAA о солнечной и геофизической активности
Количество SD 158 на уровне 2200Z 07 Jun 2005IA. Анализ активных солнечных регионов и активности от 06 - 2100Z до 07 - 2100Z Solar activity was low during the past 24 hours. There
were two C-class events. The first was a C3/Sf from Region 772
(S18W44) at 1342 UTC, and the second was a C2.5 from Region 776
(S06E47) at 1914 UTC. Neither of these regions has shown dramatic
changes during the past 24 hours. However, Region 776 continues to
be the largest group on the disk. There was some new flux emergence
and growth in Region 775 (N10E35), but the group didn't produce any
flares. A quiescent filament erupted from the northeast part of the
disk at about 0900 UTC and was associated with a CME observed by
LASCO. The CME is centered over the northeast limb and is about 75
degrees wide: it does not appear to have any earthward directed
component.
IB. Прогноз солнечной активности
Solar activity is expected to be low,
but there is a slight chance for an isolated M-class event. Regions
772 and 776 are the most likely sources for activity although Region
775 might also contribute if the current growth trend continues.
IIA. Обзор геофизической активности от 06 - 2100Z до 07 - 2100Z
The geomagnetic field ranged from quiet to minor storm levels during
the past 24 hours. The interplanetary magnetic field component Bz
went through an interval between 06/1800-07/0400 UTC with weakly but
persistently negative values ranging from 0 nT to -7 nT. This
resulted in unsettled to active levels between 06/2100-07/0300 UTC
followed by a minor storm interval from 0300-0600 UTC and another
active period from 0600-0900 UTC. Conditions have been at quiet to
unsettled levels since 0900 UTC. The greater than 2 MeV electron
flux was at high levels during the past 24 hours.
IIB. Прогноз геофизической активности
The geomagnetic field is
expected to be predominantly unsettled with a chance for isolated
active periods for the first day (08 June). Conditions should be
unsettled for the second day (09 June) and are expected to decrease
to quiet to unsettled for the third day (10 June).
