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 252 Välja antud 2200Z kuni 08 Sep 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z Solar activity was moderate. A long duration M1 flare
was observed at 08/1759Z and appeared to involve an interaction
between Region 1564 (S13W39) and Region 1562 (S21W77). Region 1564
ended the period as the largest on the visible disk, an Eai type
group with beta-gamma magnetic characteristics. A coronal mass
ejection was observed off the west limb in SOHO/LASCO C2 imagery
beginning at 08/10Z. It appeared as a full halo in STEREO-A COR2
imagery. This CME is not expected to be geoeffective.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to remain
low with a chance for an M-flare on days one and two (09-10
September), decreasing to a slight chance on day three (11
September).
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
The geomagnetic field ranged from quiet to unsettled levels, with one
period of active conditions observed at high latitudes. The solar
wind speed at the ACE spacecraft remained near 400 km/s throughout
the period. The Bz component of the interplanetary magnetic field
ranged from about +/- 5nT and earth remained in the positive sector.
A slow rise in high energy particles at ACE was observed beginning
around 09/11Z. This rise is believed to be associated with the CME
observed around 09/10Z in coronagraph imagery.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly quiet for the next three days (09-11
September).
