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 041 Välja antud 2200Z kuni 10 Feb 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 09-2100Z kuni 10-2100Z Solar activity was low due to C-class x-ray events from
Region 1415 (N08W84). Region 1416 (S17E10) continues to evolve
developing a beta-gamma magnetic configuration. New Region 1417
(N18E59) rotated onto the disk as a B-type group. As asymmetric,
full-halo CME was observed lifting off the NE limb, first seen in
SOHO LASCO C2 imagery at 09/2117Z. The source region for this event
appears to be located to the southwest of Region 1417. A second CME
was observed in STEREO-A and B COR2 imagery, first seen on the Ahead
spacecraft at 10/1154Z. The source of this CME appears to be a 23
degree long filament eruption, centered near S31E29. Analysis is
ongoing on the geoeffective potential of these CMEs.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a slight chance for M-class activity for the next three days
(11 - 13 February) due to the return of old Region 1402 (N26,
L=218).
IIA. Summaarne geofüüsikaline aktiivsus 09-2100Z kuni 10-2100Z
The geomagnetic field was at quiet to unsettled levels. ACE satellite
solar wind velocities were steady through the period at about 450
km/s. The Bz component of the interplanetary magnetic field was
mostly north at about 5 nT with brief southward excursions to -4 nT.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly quiet on day one (11 February) through midday
on day two (12 February). By midday on day two, and through day
three (13 February), field activity is expected to increase to quiet
to unsettled levels with high latitude active intervals. This
increase in activity is due to a recurrent coronal high speed stream
that is expected to rotate into a geoeffective position.
