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 248 Välja antud 2200Z kuni 04 Sep 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 03-2100Z kuni 04-2100Z Solar activity was low. Region 1564 (S14E14 -
Esi/beta-gamma) was the most active region, producing occasional
low-level C-class flares. It increased in spot count and area during
the first half of the period, but showed gradual spot and penumbral
decay during the latter half of the period. Region 1560 (N04W47 -
Eai/beta-gamma-delta) showed a slight decrease in spots and area,
but maintained a delta in its interior spots. No significant changes
were observed in the remaining spotted regions and no new regions
were numbered. No Earth-directed CME activity was observed during
the period.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
through the period (05 - 07 September) with a chance for an isolated
M-class flare.
IIA. Summaarne geofüüsikaline aktiivsus 03-2100Z kuni 04-2100Z
Geomagnetic field activity ranged from quiet to minor storm levels
with major storm periods detected at high latitudes, all due to
residual CME effects. The greater than 10 MeV proton event at
geosynchronous orbit that began at 01/1335Z, reached a maximum of 59
pfu at 02/0850Z, and ended at 04/0625Z.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic field activity is
expected to be at quiet to unsettled levels during days 1 - 2 (05 -
06 September) with a chance for active levels. This is due to the
arrival of CMEs observed on 02 September along with a co-rotating
interaction region in advance of a coronal hole high-speed stream
(CH HSS). The CMEs are expected to arrive around midday on day 1.
The CH HSS is expected to commence on day 2. Field activity is
expected to be at quiet to unsettled levels on day 3 (07 September)
as CH HSS effects subside.
