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 098 Välja antud 2200Z kuni 08 Apr 2011IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z Solar activity was at very low levels. Region 1185
(N20E14) produced a B7/Sf flare at 08/1824Z. Region 1185 was
redefined to detach two separate spot groups: Region 1185 and new
Region 1189 (N23E11). Region 1185 is now configured as a Cso group
with a beta magnetic configuration with 14 spots. New Region 1189
was numbered as a Dso group with a beta magnetic configuration with
6 spots. Region 1188 (S25W06) was numbered as a Cro group with a
beta magnetic configuration with 3 spots. Region 1187 (S18E50)
increased to a Cso group with 4 spots. Region 1183 (N14, L=140)
rotated off the limb. A back-sided full-halo CME was observed on
SOHO/LASCO C3 imagery at 07/2342Z.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low to low levels for the next three days (09-11 April).
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
The geomagnetic field was predominantly quiet, with isolated
unsettled levels.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled levels, with active levels at
high latitudes on day one (09 April). Quiet to unsettled levels are
expected, with isolated active levels at mid latitudes and minor
storm levels at high latitudes, on days two and three (10-11 April).
The increase in activity is due to a coronal hole high-speed stream.
