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 251 publié à 2200Z le 08 Sep 2011IA. Analyse des régions solaires actives et activité du 07-2100Z au 08-2100Z Solar activity was high. Region 1283 (N16W42) produced
two major flares. The first was an X1/3b at 07/2238Z associated with
weak Types II and IV radio sweeps, a 1300 sfu Tenflare, and a
non-Earth-directed CME. The second was an M6/1n at 08/1546Z
associated with a weak Type IV radio sweep. Region 1283 maintained a
weak delta magnetic within the northern portion of its leader spots
and showed trailer spot development during the period. Region 1289
(N21E51) also showed trailer spot development during the period. No
new regions were numbered.
IB. Prévisions d'activité solaire
Solar activity is expected to be
moderate during the period (09 - 11 September) with a chance for
another X-class flare from Region 1283.
IIA. Résumé de l'activité géophysique du 07-2100Z au 08-2100Z
Geomagnetic field activity was at quiet levels. The greater than 2
MeV electron flux at geosynchronous orbit reached high levels during
the period.
IIB. Prévision de l'activité géophysique
Geomagnetic field activity is
expected to be at quiet levels until late on day 1 (09 September).
Activity is expected to increase to unsettled levels late on 09
September with a chance for active levels due to a CME arrival. A
further increase to unsettled to active levels with a chance for
minor storm levels is expected on day 2 (10 September) as the CME
passage continues. A decrease to unsettled levels is expected on day
3 (11 September). There will be a chance for a greater than 10 MeV
proton event at geosynchronous orbit on day 1.
