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 113 Välja antud 2200Z kuni 23 Apr 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z Solar activity increased to high levels this period.
Region 338 (N18W32) produced an M5/1n flare at 23/0106Z. Type II
(513 km/s) and Type IV radio sweeps, and a 380 sfu tenflare were
associated with this event. A partial halo CME was also detected on
LASCO imagery. An M2/1f flare also occurred in this region at
23/1556Z. This complex region continues to develop in both size and
magnetic complexity. Region 339 (N16W84) was quite active as it
approaches the west limb. It produced several C-class flares, the
largest being a C5 flare at 23/1213Z. No significant changes were
observed in the remaining active regions. New Region 343 (N06E60)
was numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
moderate levels. Region 338 maintains potential for further M-class
activity.
IIA. Summaarne geofüüsikaline aktiivsus 22-2100Z kuni 23-2100Z
The geomagnetic field ranged from quiet to active levels with
isolated minor storm periods at high latitudes. Elevated solar wind
speeds near 500 km/s are responsible for the disturbed periods. The
greater than 2 MeV electrons at geosynchronous orbit reached high
levels again today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at unsettled to minor storm levels. Ongoing high
speed coronal hole flow will likely be enhanced by transient flow
over the next three days. Weak impact from the April 22, M2 flare
and CME are possible on day one. There is a higher probability for
CME impacts on days two and three from the M5 and associated CME
that occurred early this period.
