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 175 publié à 2200Z le 24 Jun 2001IA. Analyse des régions solaires actives et activité du 23-2100Z au 24-2100Z Solar activity has been at low levels. The largest
event being an optically uncorrelated C6 at 24/0455 UTC. Region 9511
(N10E00), after producing an X-class flare and three M-class events
on 22-23 June, has shown a dramatic decrease in activity and has
deteriorated to a simple beta magnetic classification. Only two
minor C-class events were produced by Region 9511 today. Region 9503
(N15W75) still retains a beta-gamma classification, but has only
produced a minor C-class event during the period. Regions 9512
(S22W09) and 9513 (N23E44) have increased in area and spot count but
have not produced any significance activity yet. No new regions were
numbered.
IB. Prévisions d'activité solaire
Solar activity is expected to be low
to moderate. Isolated M-class events are possible.
IIA. Résumé de l'activité géophysique du 23-2100Z au 24-2100Z
The geomagnetic field was at quiet to unsettled conditions. The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be at quiet to unsettled conditions for the first two
days of the period. Isolated active conditions, especially at higher
latitudes, may occur on the third day due to a favorably positioned
coronal hole and the resulting high speed stream impacting earth.
