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 210 Välja antud 2200Z kuni 28 Jul 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 27-2100Z kuni 28-2100Z Solar activity has declined to low levels. Region 652
(N08W76) continues to be quite active and produced several C-class
events this period. The most important was a very long duration C4
enhancement that began around 28/0200Z and lasted for 10 hours.
LASCO imagery showed a large CME off the west limb originating from
near Region 652. Though most of the ejecta was westward directed, a
glancing blow is possible from this CME. Region 652 continues to
slowly decay, but still maintains considerable size and magnetic
complexity. No other significant changes were noted.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be very
low to moderate. Region 652 still has potential for an M-class flare
before it rotates around the west limb on 29 July. Expect levels to
decrease to very low to low by 30 July.
IIA. Summaarne geofüüsikaline aktiivsus 27-2100Z kuni 28-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The
period began with minor storm levels in the waning stages of
yesterday's severe geomagnetic storm. By 28/0300Z, the IMF Bz was
near zero and the geomagnetic field responded with quiet to
unsettled conditions for the remainder of the period. Solar wind
speed was elevated near 900 km/s at the beginning of the period, but
gradually declined to 600 km/s. The greater than 10 MeV proton
event that began on 25/1855Z, ended on 28/0040Z. The greater than 2
MeV electron flux at geosynchronous orbit was at very high levels
today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be quiet to unsettled on 29 July. Today's CME off the
southwest limb is expected to produce unsettled to minor storm
periods late on 30 July. A gradual return to quiet to unsettled
conditions is expected on 31 July.
