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 211 Välja antud 2200Z kuni 29 Jul 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 28-2100Z kuni 29-2100Z Solar activity was at moderate levels today. Region
652 (N08W89) produced the largest event of the period, an M2 x-ray
flare that occurred at 29/0006Z. Although, the most significant
event during the period was a long duration C2 x-ray flare. There
was an associated partial halo CME with this flare that may result
in an glancing blow from the anticipated transient passage. The
beta-gamma magnetic structure remains unchanged as Region 652
rotates beyond the solar west limb. Region 654 (N08W02) was
quiescent today and is the only other spotted active region on the
visible disk. No new regions were numbered today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low to moderate levels. Region 652 may yet produce another
M-class flare before rotating completely beyond the solar west limb
through day one (30 July). Expect activity to decrease to very low
to low levels by 31 July.
IIA. Summaarne geofüüsikaline aktiivsus 28-2100Z kuni 29-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron flux at geosynchronous orbit reached very high
levels today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to range from quiet to minor storm levels throughout the
period. The elevated conditions are expected due to the anticipated
shock passages from the CME activity seen on LASCO imagery from the
long duration C4 that occurred early yesterday and the C2 that
occurred today.
