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 212 Välja antud 2200Z kuni 30 Jul 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 29-2100Z kuni 30-2100Z Solar activity decreased to low levels today. Old
Region 652 (N08, L=348) has rotated beyond the western solar limb
although it was the source for the C-class flare activity seen
earlier in the period. Region 654 (N08W15) went unchanged in spot
area and magnetic complexity. Several lesser B-class flares were
produced from this region today. Region 655 (S09E71) was numbered
today.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be at
very low to low levels. Region 654 is capable of producing C-class
flares.
IIA. Summaarne geofüüsikaline aktiivsus 29-2100Z kuni 30-2100Z
The geomagnetic field was at quiet to unsettled levels. A shock
passage was observed at the ACE spacecraft at approximately 30/2030Z
and is believed to be in response to the very long duration C4 x-ray
flare that occurred at 28/0609Z. A sudden impulse of 25 nT occurred
at the Boulder magnetometer at 30/2115Z. The greater than 2 MeV
electron flux at geosynchronous orbit reached very high levels again
today.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at quiet to unsettled levels. A transient passage
may occur late on 31 July into 1 Aug allowing for isolated active
conditions resulting from the long duration C2 x-ray flare that
occurred on 29 July. Quiet levels are expected to return late on 1
Aug.
