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 010 Välja antud 2200Z kuni 10 Jan 2002IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 09-2100Z kuni 10-2100Z Solar activity was low. Region 9773 (N14W17) belied its
ominous appearance in white light and h-alpha by producing just
C-class events in the past 24 hours. A C7/Sf at 1018 UTC was the
largest event, although the x-ray background from GOES was enhanced
throughout the day. The region measures more than 500 millionths in
white light, and retains a significant degree of magnetic
complexity. Elsewhere, Region 9778 (S17E45) grew in most parameters
and produced occasional subflares.
IB. Päikese aktiivsuse ennustus
Solar activity is expected to be
moderate. Region 9773 is capable of M class activity.
IIA. Summaarne geofüüsikaline aktiivsus 09-2100Z kuni 10-2100Z
The geomagnetic field varied from quiet to minor storm levels. A high
speed solar wind stream began to impact the magnetosphere early in
the period, with solar wind speeds increasing from 350 km/s to more
than 600 km/s. In addition, there have been intervals where the
interplanetary magnetic field has been near 20 nT southward, further
fueling the disturbance. An enhancement in the greater than 10 MeV
protons at GOES began around 0700 UTC. The flux attained event level
(10 pfu at greater than 10 MeV) at 2045 UTC. This increase may be
associated with east limb activity that occurred late on January 8.
IIB. Geofüüsikalise aktiivsuse ennustus
The geomagnetic field is
expected to be at active to minor storm levels. The current
disturbance should persist for the next 24-48 hours. The greater
than 10 MeV proton event is likely to slowly decay.
