Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 223 Välja antud 2200Z kuni 10 Aug 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 09-2100Z kuni 10-2100Z Solar activity was low. Two C-class events were
observed from Region 1542 (S16E24); the largest was a C4/Sf at
10/0416Z. Region 1544 (S29W20) also produced a C2/Sf flare at
10/1740Z. Region 1543 (N21E33) was the largest region on the disk
and produced some B-class events during the period. The remaining
regions were quiet and stable, with no significant changes since
yesterday. No earth-directed CMEs were observed.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a slight chance for an M-class event from Region 1542.
IIA. Summaarne geofüüsikaline aktiivsus 09-2100Z kuni 10-2100Z
The geomagnetic field was quiet. Solar wind speed at the ACE
spacecraft remained near 350 km/s and the Bz component of the
interplanetary magnetic field was mostly neutral.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled levels, with a slight chance
for an isolated active period for days 1 and 2 (11-12 August). This
elevated activity is expected in response to the arrival of a
corotating interaction region and coronal hole, coupled with two
filaments that lifted off on 07 and 08 August. On day 3 (13 August)
conditions are expected to return to quiet levels.
