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 184 Välja antud 2200Z kuni 03 Jul 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 02-2100Z kuni 03-2100Z Solar activity was low. Regions 397 (N12E00) and 400
(N05E44) produced a few C-class flares during the past 24 hours. The
largest of these was a C5 at 02/2222 UTC from Region 400. Region 400
was active all day and has a dominant northeast-to-southwest
inversion line. Region 397 showed growth in the trailer portion of
the group, leading to the formation of two small delta
configurations.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate. There is a good chance for M-class flare activity from
Region 397. In addition, the magnetic structure of Region 400
suggests that it is likely to build shear and this should lead to
frequent subflare activity.
IIA. Summaarne geofüüsikaline aktiivsus 02-2100Z kuni 03-2100Z
The geomagnetic field ranged from quiet to active levels. Solar wind
speeds increased up to around 600 km/s at 02/2300 UTC, but dropped
down to 500-550 km/s from 0100-1900 UTC. However, there appears to
be another solar wind speed increase in progress at this time. The
greater than 2 MeV electron fluxes were at high levels during the
past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly active for the next two days in response to a
favorably positioned coronal hole. There may also be isolated
periods of storm level activity. A gradual decline to unsettled to
active is expected on the third day.
