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 072 Välja antud 2200Z kuni 12 Mar 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 11-2100Z kuni 12-2100Z Solar activity was low. Region 570 (S14W05) produced an
impulsive C3/Sf at 12/0237Z with minor centimetric radio bursts. The
large leading sunspot cluster in this region began to fragment this
period and the trailing spots have decayed considerably; however, a
weak delta configuration is still evident. A new bipolar sunspot
group formed north and center on the disk and was numbered as Region
572 (N19W05). New Region 573 (S14E71) was also numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to continue
at low levels. Occasional C-class activity is expected from Region
570 with a slight chance of an M-class flare.
IIA. Summaarne geofüüsikaline aktiivsus 11-2100Z kuni 12-2100Z
The geomagnetic field ranged from quiet to minor storm levels. A high
speed stream associated with a large transequatorial coronal hole
is responsible for the current disturbance. The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels again
today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to range from quiet to active with isolated minor storm
periods possible. The coronal hole high speed stream is expected to
continue through 13 March. Mostly quiet to unsettled, with isolated
active periods are expected on 14 and 15 March as the high speed
stream subsides.
