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 313 Välja antud 2200Z kuni 08 Nov 2012IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
08/0223Z from Region 1611 (N12E66). The M1 event was associated with a
CME off the east limb (not expected to be geoeffective) and a type II
radio sweep. A backsided, full-halo CME was observed later in the day
(first entering the C2 field of view at 08/1112Z); Stereo imagery
indicated that old Region 1598 was the source. There are currently 6
numbered sunspot regions on the disk
including two newly numbered groups: Region 1611 (N12E66) and 1612
(N06E71).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at low
levels with a slight chance for moderate levels on days one, two, and
three (09 Nov, 10 Nov, 11 Nov).
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 557 km/s at
07/2122Z, consistent with a coronal hole high speed stream. Total IMF
reached 5.3 nT at 08/0250Z. The maximum southward component of Bz
reached -2.9 nT at 08/1953Z. Solar wind velocity was steadily decreasing
during the latter part of the day.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is expected
to be at quiet levels for the next three days (09 Nov, 10 Nov, 11 Nov).
