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 198 Välja antud 2200Z kuni 16 Jul 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 15-2100Z kuni 16-2100Z Solar activity was high. Region 649 (S10E26) produced
three X-class flares: an X1 at 0206 UTC, an X1/1f at 1041 UTC, and
an X3/3b at 1355 UTC. All of these events were impulsive and none
were associated with an obvious CME in the LASCO data. However, a
weak type II radio sweep was observed in association with the X3
event. Region 649 has shown some consolidation of spots in the
leader and in the trailer areas and the region is maintaining
complexity - the delta configuration in the dominant trailer
penumbra continues to be the primary location for the flare
activity. Two new regions are just visible on the east limb in
GOES-12 SXI images at S11 and N05. The region to the north rotated
into view at (N05E88) and was assigned SWO region number 652.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate to high. Region 649 is expected to continue to produce
M-class flares and has a fair chance for producing more major flare
activity during the next three days (17-19 July). These events could
become geoeffective (i.e. earthward directed CMEs or proton events)
as the region evolves and as it moves near central meridian and into
the western hemisphere.
IIA. Summaarne geofüüsikaline aktiivsus 15-2100Z kuni 16-2100Z
The geomagnetic field was mostly quiet to unsettled, although there
was one active period from 2100-2359 on 15 July.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly unsettled for the next three days (17-19
July). As noted previously, however, there is a possibility that
Region 649 could produce some events that could increase geomagnetic
activity during the forecast interval.
