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 145 Välja antud 2200Z kuni 24 May 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 23-2100Z kuni 24-2100Z Solar activity was at low levels today. Region 618
(S10E13) produced the largest flare of the period, a C4 x-ray event
that occurred at 24/1104Z. There was a continued growth in sunspot
area and the total spot count today. A continued emergence of flux
now shows several delta structures near region center in this
magnetic beta-gamma-delta group. The remaining active regions were
quiescent today. No new regions were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low to moderate levels. Due to continued growth in magnetic
complexity, Region 618 has the potential of producing M-class flare
activity.
IIA. Summaarne geofüüsikaline aktiivsus 23-2100Z kuni 24-2100Z
The geomagnetic field ranged from quiet to active levels. The high
speed solar wind stream continues to persist while solar wind speeds
were exceeding 500 km/s late in the period.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at predominantly quiet to unsettled levels. Isolated
active conditions are possible through 25 May as the geoeffective
high speed coronal hole stream begins to wane. NOTE: The ACE
spacecraft orbit will bring ACE nearly in line with the Sun from
about May 30 to June 2, 2004. During that time solar radio noise is
expected to interfere with spacecraft telemetry resulting in the
loss of solar wind plasma, magnetic field, and particle data.
