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 099 publié à 2200Z le 08 Apr 2004IA. Analyse des régions solaires actives et activité du 07-2100Z au 08-2100Z Solar activity was low. Region 588 (S16W13) produced a
C7/Sf flare at 08/1019Z. This event had an associated tenflare (190
sfu) and a full halo CME on LASCO imagery. No significant changes
were observed in Region 588, which maintains a reverse polarity
beta magnetic configuration. Coronal mass ejections were also
observed to originate from behind the northwest limb. The first of
these CMEs occurred at 08/0148Z and had an associated Type II radio
sweep (709 km/s). A long duration x-ray enhancement accompanied the
second CME at around 08/1900Z. No other significant changes or
activity were observed.
IB. Prévisions d'activité solaire
Solar activity is expected to continue
at low levels. Region 588 is expected to produce occasional C-class
activity.
IIA. Résumé de l'activité géophysique du 07-2100Z au 08-2100Z
The geomagnetic field was mostly quiet to active with isolated minor
storm periods during local nighttime hours.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to range from quiet to minor storming. There has been no
obvious transient passage at ACE yet from the full halo CME observed
on LASCO imagery on 6 April. Occasional minor storm periods are
expected in the next 24 hours from this CME. Another full halo CME
was observed today and is expected to produce active to minor storm
periods on 11 April.
