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 008 Välja antud 2200Z kuni 08 Jan 2004IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z Solar activity was moderate due to an M1/1n flare at
0507 UTC from Region 537 (N04E50). The group produced additional
small flares throughout the day. Analysis of the region indicates a
small, relatively compact group of spots with an inversion line
running northeast to southwest and cutting through penumbra, making
this a delta class group. Region 536 (S10W16) continues to be the
largest group and also has a delta configuration. The region
produced a few small flares during the past 24 hours and is slowly
decaying. A CME was reported by LASCO over the south solar pole,
beginning at 1654 UTC on the 7th, and associated with subsequent
relatively faint, large scale post-eruption loop system (visible in
EIT 195) just to the west and south of Region 536.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate for 09-11 January with Regions 536 and 537 being the most
likely source for activity. There continues to be a slight chance
for a major flare or proton producing flare from either of these
regions during the 09-11 January forecast period.
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
The geomagnetic field was quiet to unsettled. ACE solar wind showed a
steady decline of solar wind velocity and Bz was mostly weak during
the past 24 hours. The solar wind appears to be transitioning to
nominal conditions, probably indicating the end of the recent high
speed stream at ACE. The greater than 2 MeV electron fluxes were
high during the past 24 hours.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be generally unsettled for 09-11 January with a slight
chance for isolated active periods.
