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 068 Välja antud 2200Z kuni 09 Mar 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 08-2100Z kuni 09-2100Z Solar activity was moderate. Two M1 x-ray flares were
observed from Region 1166 (N09W12) which was an Ekc spot group with
a Beta-Gamma-Delta magnetic classification. The area of this region
and the number of spots increased over the last 24 hours. Region
1169 (N20E18) also grew in area and number of spots over the past 24
hours, ending the period as an Esc type spot group with a Beta-Gamma
magnetic classification. The remaining regions were either small
and magnetically simple (Region 1170) or decaying (Region 1164) and
rotating off the visible disk.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to remain
moderate for day 1 (10 March) with a chance for M-class activity
from Region 1166 or Region 1169.
IIA. Summaarne geofüüsikaline aktiivsus 08-2100Z kuni 09-2100Z
The geomagnetic field was quiet. The greater than 10 MeV proton flux
remained above the 10 pfu threshold throughout the past 24 hours.
Solar wind speed measured at the STEREO-A spacecraft jumped from
approximately 650 km/s to 870 km/s near 09/0700Z. This jump was
accompanied by southward Bz to -20nT. These observations were
consistent with a shock passage from the CME that originated on
07/2012Z. 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 unsettled to active, with isolated minor storm
periods possible at high latitudes on day one (10 March), and
primarily unsettled conditions on days two and three (11-12 March).
The CME from 07 March is expected to arrive mid-day on 10 March,
leading to the elevated activity.
