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 192 Välja antud 2200Z kuni 11 Jul 2003IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 10-2100Z kuni 11-2100Z Solar activity decreased to low levels today. Several
minor B and C-class flares were observed during the period. Even
though Region 397 (N12, L=028) has rotated beyond the west limb it
managed to produce most of the recorded C-class activity. Region
401 (S09W05) produced the largest flare of the period, a C2.9 that
occurred at 11/0739Z. This region has doubled in penumbral coverage
during the interval although it remains simply structured. Region
400 (N06W65) was quiescent while undergoing steady decay. The
magnetic gamma structure remains vaguely intact. Regions 405
(S10E66), 406 (S19W11), and 407 (N09E31) were newly assigned today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
low levels. With continued growth, Region 401 may become capable of
producing isolated M-class flares.
IIA. Summaarne geofüüsikaline aktiivsus 10-2100Z kuni 11-2100Z
The geomagnetic field was at quiet to major storm levels. An
extended period of southward Bz (-10 nT) led to the elevated
conditions. An isolated period of major storm levels was observed
between 11/0600 and 11/0900Z. An increase in the solar wind speed
began near mid-period and is likely to be the onset of a recurrent
coronal hole.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at predominantly unsettled to active levels.
Isolated minor storm conditions may occur at both middle and high
latitudes, especially during nighttime hours due to high speed
coronal hole stream effects throughout the period. Day three may
see further elevated conditions due to an anticipated transient
passage from the M3.6 x-ray flare that occurred on 10 July.
