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 103 Välja antud 2200Z kuni 13 Apr 2005IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 12-2100Z kuni 13-2100Z Solar activity was very low. All of the regions on the
disk were stable and quiet, and the GOES x-ray flux remained below B
level for the entire interval. New Region 753 (N12W06) emerged as
a small, C-type sunspot group.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low to low.
IIA. Summaarne geofüüsikaline aktiivsus 12-2100Z kuni 13-2100Z
The geomagnetic field was mostly active with a few minor storm
periods. The enhanced activity is being driven by a high speed
stream from a favorably positioned coronal hole. The greater than 2
MeV electron flux attained high levels during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be unsettled to active for the next 24 hours (14 April).
The currently enhanced activity level is expected to diminish around
midday on the 14th as the high speed stream moves out of
geoeffective position. Mostly unsettled levels should predominate on
15 April, and quiet to unsettled conditions are expected for 16
April.
