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 080 Välja antud 2200Z kuni 21 Mar 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 20-2100Z kuni 21-2100Z Solar activity increased to low levels. Isolated
C-class flares were observed, the largest of which was a
long-duration C4 at 21/1719Z from newly-numbered Region 1176
(S13E81). Region 1176 was the return of old Region 1165, which
produced M-class flares during its previous rotation. SOHO/LASCO
images showed a halo-CME, first visible in C2 images at 21/0236Z.
The halo-CME was determined to be a backside event associated with a
flare from old Region 1169 (N20, L=061).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
during days 1 - 3 (22 - 24 March) with a chance for an M-class flare
from Region 1176.
IIA. Summaarne geofüüsikaline aktiivsus 20-2100Z kuni 21-2100Z
Geomagnetic field activity was at quiet levels. A greater than 10 MeV
proton event at geosynchronous orbit began at 21/1950Z and was in
progress at the time of this report. Stereo-A EUVI 195 images
indicated the source for the proton event was likely a flare from
old Region 1169 which also spawned the back sided halo-CME mentioned
above.
IIB. Geofüüsikalise aktiivsuse ennustus
Geomagnetic activity is
expected to be at quiet levels during days 1 - 2 (22 - 23 March).
Geomagnetic activity is expected to increase to quiet to unsettled
levels on day 3 (24 March) as a coronal hole high-speed stream
begins to disturb the field. The greater than 10 MeV event at
geosynchronous orbit is expected to end on day 1 (March 22).
