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 259 Välja antud 2200Z kuni 15 Sep 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z Solar activity was very low. Low-level B-class x-ray
flares occurred during the period. Region 1566 (N23W76 - Hrx/alpha)
produced occasional B-class flares as it approached the west limb.
Occasional B-class flares also occurred from a yet-to-be-numbered
small spot group that rotated into view late in the period. Region
1569 (S12W00 - Eao/beta-gamma) showed minor spot growth in its
trailer portion and retained a beta-gamma magnetic configuration.
New Region 1572 (N15W70 - Axx/alpha) was numbered. There was no
Earth-directed CME activity observed during the period.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low during days 1 - 3 (16 - 18 September) with a chance for isolated
C-class flares.
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
The geomagnetic field was at quiet to (briefly) unsettled levels.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to increase to unsettled levels around midday on day 1 (16
September) with a chance for active levels due to the arrival of the
CME associated with the filament disappearance observed on 13
September. Field activity is expected to decrease to quiet to
unsettled levels on day 2 (17 September) as CME effects subside. A
further decrease to quiet levels is expected on day 3 (18
September).
