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 273 Välja antud 2200Z kuni 30 Sep 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity was moderate. Region 1305 (N12E01)
produced an M1/1f at 30/1906Z. A Type II Radio Sweep (estimated
speed 690 km/s) was associated with this event along with a 260 sfu
tenflare. Region 1305 has shown slight aerial and penumbral growth
and maintains a beta-gamma magnetic configuration. Region 1302
(N13W29) produced a C1/Sf at 30/0252Z and has a beta-gamma-delta
magnetic configuration. Region 1307 (N14E48) has grown slightly and
produced a C3 at 30/1847Z.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with M-class activity likely through the period (01-03 October),
mainly from Regions 1302 and 1305. There is a slight chance for
X-class activity from these regions as well.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
The geomagnetic field was quiet during the past 24 hours. The greater
than 2 MeV electron flux at geosynchronous orbit reached high levels
during the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled with a slight chance for isolated
active periods on days one and two (01-02 October). The increase in
activity is expected due to the anticipated arrival of a recurrent
coronal hole high speed stream (CH HSS) on day one and possible
effects on day two from a weak CME associated with the long duration
C2 event observed on 29 September. Mostly quiet conditions are
expected on day three (03 October).
