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 042 Välja antud 2200Z kuni 11 Feb 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 10-2100Z kuni 11-2100Z Solar activity was low due to a trio of C7 x-ray
events. Regions 1416 (S19W02) and 1417 (N16E44) each produced C7
events at 10/2352Z and 11/1854Z respectively. The third C7 event was
observed at 11/1004Z from behind the east limb near N25. The
activity behind the NE limb portends the return of old Region 1402
(N26, L=218). Region 1416 continued its growth phase, both in area
and spot count, and maintained a beta-gamma magnetic configuration.
At about 10/1900Z, a 27 degree long segmented filament erupted in
the NE quadrant of the disk. The ENE to WSW oriented filament was
centered at N29E14. An associated CME was observed lifting of the NE
limb, first visible in SOHO LASCO C2 imagery at 10/2012Z.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
with a chance for M-class activity for the next three days (12 - 14
February).
IIA. Summaarne geofüüsikaline aktiivsus 10-2100Z kuni 11-2100Z
The geomagnetic field was at quiet to unsettled levels. ACE solar
wind speeds decreased steadily through the period from 450 km/s to
about 350 km/s. The Bz component of the interplanetary magnetic
field did not vary much beyond +/- 3 nT.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled levels on days one and two (12
- 13 February) due to coronal hole high speed stream effects. Late
on day two and through day three (14 February), field activity is
expected to increase to unsettled to active levels, with high
latitude minor storm intervals. This increase in activity is due to
anticipated effects from the 10 February CME.
