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 102 Välja antud 2200Z kuni 12 Apr 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 11-2100Z kuni 12-2100Z Solar activity was low due to a C2/Sf flare at 1721 UTC
from newly assigned Region 752 (N00E76). There were additional
B-class events during the past 24 hours and all of these were from
752 as well. At this time Region 752 is a small, D-type sunspot
region.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be low
for the next three days (13-15 April).
IIA. Summaarne geofüüsikaline aktiivsus 11-2100Z kuni 12-2100Z
The geomagnetic field ranged from quiet to major storm levels.
Conditions were at mostly active to minor storm levels during the
past 24 hours with a major storm interval at high latitudes from
0000-0300 UTC. The enhanced activity is being driven by a favorably
positioned coronal hole.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly active for the next 36 hours (13 April to 14
April 1200 UTC) due to persistent coronal hole effects. Conditions
should begin to decline partway through the 14th and should be quiet
to unsettled by the 3rd day (15th).
