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 071 Välja antud 2200Z kuni 12 Mar 2010IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 11-2100Z kuni 12-2100Z Solar activity was low due to a C2/Sf flare at 12/1827Z
from Region 1054 (N15E29). Region 1054 continues to show a slow
growth trend. Region 1055 (S24W27) was quiet and mostly unchanged
during the past 24 hours. A CME was observed on the east limb at
about 11/2330Z and appeared to be associated with the eruption of a
filament in the northeast quadrant.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low.
Additional C-flares are likely from Region 1054. There is a slight
chance for an isolated M-class event from this region.
IIA. Summaarne geofüüsikaline aktiivsus 11-2100Z kuni 12-2100Z
The geomagnetic field was mostly quiet to unsettled at mid-latitudes,
with one active period at some stations from 0300-0600Z. The high
latitudes observed quiet to active levels with some isolated storm
periods between 0300-0600Z, and from 1200-1500Z. Solar wind
velocities remained elevated through the period, generally ranging
between 500-580 km/s. There appeared to be a decreasing trend during
the last 4 hours of the period, with day-end speed values around 480
km/s. The solar wind signatures are consistent with a high speed
stream from the southward extension of the northern polar coronal
hole. The greater than 2 MeV electron flux reached high levels
during the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly unsettled with a chance for isolated active
periods for the first day (13 March) due to persistence. Quiet to
unsettled levels (with a chance for active periods) are expected on
days two and three (14-15 March) due to possible effects from a
recurrent solar sector boundary.
