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 197 Välja antud 2200Z kuni 16 Jul 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 15-2100Z kuni 16-2100Z Solar activity was low. Today's activity consisted of
three, low-level C-class flares from Region 410 (S12E28). This group
showed emerging flux and has developed some magnetic complexity.
However, the field intensity and sunspot area are still relatively
small. Region 409 (N16E27) continues to be the largest group on the
disk but showed overall decay and some simplification. Region 409
was quiet and stable during the past 24 hours. Two new regions were
assigned today: Region 412 (N16E19) and Region 413 (N18E49).
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
predominantly low. There continues to be a chance, however, for an
isolated M-class event over the next three days. Region 409 is the
most likely source for energetic flares, but Region 410 might also
produce an M-flare if the current growth trend continues.
IIA. Summaarne geofüüsikaline aktiivsus 15-2100Z kuni 16-2100Z
The geomagnetic field ranged from active to major storm levels. An
initially active field attained storm levels after 0300 UTC and
continued at storm levels through 1500 UTC. Conditions returned to
active levels from 1500 UTC through the end of the period. The
increase in activity was associated with a slight increase in solar
wind speed (600 to 650 km/s) and a noticeable increase in total
magnetic field in the solar wind (ranging from 10 to 15 nT). The
solar wind signatures are consistent for the most part with a high
speed solar wind stream originating from a favorably positioned
coronal hole.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be mostly active with minor storm periods during the
next 24 hours as the current disturbance persists. A decrease to
unsettled to active is expected on the second and third days as the
high speed solar wind should gradually decline.
