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 250 Välja antud 2200Z kuni 06 Sep 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 05-2100Z kuni 06-2100Z Solar activity was moderate. Region 1560 (N04W73 -
Eai/beta-gamma) produced an impulsive M1 x-ray flare at 06/0413Z as
well as occasional low-level C-class flares. No obvious changes were
noted in Region 1560, but limb proximity hampered analysis. Region
1564 (S14W13 - Esi/beta) also produced occasional low-level C-class
flares. It showed minor spot and penumbral growth in its interior
portion. Region 1562 (S22W48 - Dso/beta) showed gradual spot and
penumbral growth during the period. No new regions were numbered. No
Earth-directed CME activity occurred during the period.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
through the period (07 - 09 September) with a chance for an isolated
M-class flare on day 1. There will be a slight chance for an
isolated M-class flare during days 2 - 3.
IIA. Summaarne geofüüsikaline aktiivsus 05-2100Z kuni 06-2100Z
Geomagnetic field activity ranged from quiet to active levels. Active
levels occurred during 06/0000 - 0300Z due to periods of southward
IMF Bz and enhanced IMF Bt associated with a solar sector boundary
change. Field activity decreased to mostly quiet levels after
06/0300Z.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to be at quiet levels through the period (07 - 09
September) with a chance for unsettled levels.
