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 288 Välja antud 2200Z kuni 14 Oct 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z Solar activity was low. The largest flare of the
period, a C4 at 14/0230Z, occurred from a region just beyond the
northeast limb. New flux emergence was observed in the northeast
quadrant and was numbered Region 1592 (N23E20). An asymmetric halo
CME was observed in SOHO/LASCO C2 imagery beginning at 14/0048Z.
Correlation with STEREO B EUVI and COR2 imagery determined it was a
backside event.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a chance for an isolated M-class flare during the forecast
period (15-17 October).
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
The geomagnetic field was at quiet to minor storm levels. An
isolated minor storm period was observed during the 14/0000-0300Z
period. Solar wind speed, measured at the ACE spacecraft, declined
from approximately 590 km/s to 490 km/s while the Bz component of
the interplanetary magnetic field did not vary much beyond +/- 5 nT.
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 mostly unsettled with a chance for active periods on
day 1 (15 October) as effects from the coronal hole high speed
stream wane. On days 2-3 (16-17 October), quiet to unsettled
conditions are expected.
