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 160 publié à 2200Z le 09 Jun 2005IA. Analyse des régions solaires actives et activité du 08-2100Z au 09-2100Z Solar activity was at low levels. Region 775 (N08E08)
produced the largest event of the period which was a long duration
C1.5 x-ray flare that occurred at 09/1334Z. This region underwent
continued growth in sunspot area during the period with the eastern
most delta structure from yesterday becoming detached from the
dominant central spot. Although the delta structure to the south
remains well intact. Region 776 (S06E20) produced a C1 x-ray flare
that occurred at 09/1631Z and white light analysis showed minor
growth in sunspot area. Region 772 (S18W71) appears to have
continued to decay and was quiescent throughout the day. No new
regions were numbered today.
IB. Prévisions d'activité solaire
Solar a activity is expected to be at
low levels. Regions 775 and 776 may both be capable of producing an
isolated low level M-class flare.
IIA. Résumé de l'activité géophysique du 08-2100Z au 09-2100Z
The geomagnetic field was at quiet to unsettled levels. 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 at predominantly quiet to unsettled levels.
Beginning late on 11 June, active conditions may occur due to the
arrival of the faint partial halo CME that was observed yesterday.
