Rapport d'activité solaire
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.

Rapport de l'USAF/NOAA sur l'activité solaire et géophysique
SDF numéro 164 publié à 2200Z le 13 Jun 2005IA. Analyse des régions solaires actives et activité du 12-2100Z au 13-2100Z Solar activity was very low. Regions 775 (N10W46) and
776 (S06W34) are both in decay. LASCO imagery showed a CME at
13/1600 UTC. The ejecta was directed to the north west and is not
likely to be geoeffective.
IB. Prévisions d'activité solaire
Solar activity is expected to be very
low to low.
IIA. Résumé de l'activité géophysique du 12-2100Z au 13-2100Z
The geomagnetic field was at unsettled to major storm conditions.
Periods of major storming levels were observed at 12/2100 - 2400 UTC
and again at 13/0300 - 0600 UTC. Heightened activity was due to a
prolonged southward Bz in response to CME activity from 08 June. By
the end of the period conditions had quieted down to unsettled
levels and the Bz component of the Magnetic field did not vary
beyond +/- 5 Nt. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels today.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be mostly unsettled on 14 June. The arrival of a CME
associated with C-class X-ray activity early on 12 June is expected
early on 15 June causing unsettled to active conditions with periods
of minor storming possible. Activity is expected to settle down to
quiet to active levels on 16 June.
