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 084 Välja antud 2200Z kuni 25 Mar 2010IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 24-2100Z kuni 25-2100Z Solar activity has been at very low levels for the past
24 hours. Region 1057 (N15E45) has shown steady growth in area (400
millionths) and is still classified as a D group. Several B-class
flares were observed from Region 1057, the largest being a B7,
optically uncorrelated event, at 25/0433Z. A far-sided CME was
observed at 25/0128Z with an associated Type II radio sweep (shock
velocity 1395 km/s), but does not look to be geoeffective. Region
1058 (N27W06) was numbered today and is classified as a simple A
group.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low to low levels. There is a chance for C-class flares from
Region 1057.
IIA. Summaarne geofüüsikaline aktiivsus 24-2100Z kuni 25-2100Z
The geomagnetic field has been at quiet to unsettled levels for the
past 24 hours. Solar wind observations from the ACE spacecraft
showed an increase of wind speed from 300 to 430 km/s following a
rise in density (1 to 22 p/cc). These signatures are indicative of a
co-rotating interactive region in advance of a weak coronal hole
high-speed stream.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to remain at quiet to unsettled levels for day one (26
March) as the effects of the coronal hole high-speed stream subside.
On day two (27 March), quiet levels are expected. On day three (28
March), the geomagnetic field is expected to be at quiet to
unsettled levels as a new coronal hole high-speed stream becomes
geoeffective.
