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 181 publié à 2200Z le 30 Jun 2003IA. Analyse des régions solaires actives et activité du 29-2100Z au 30-2100Z Solar activity was low. Today's activity was
characterized by occasional C-class flares. Most of these were from
Region 396 (S06W54). Region 397 (N11E40) is the largest, most
complex group on the disk but only produced two C-class flares
during the past 24 hours. New Regions 398 (N04E66) and 399 (N15E52)
were assigned today.
IB. Prévisions d'activité solaire
Solar activity is expected to be
mostly low, but with a chance for an isolated M-class event sometime
during the next three days. Regions 396 and 397 are the most likely
sources for energetic flare activity.
IIA. Résumé de l'activité géophysique du 29-2100Z au 30-2100Z
The geomagnetic field ranged from unsettled to minor storm levels
during the past 24 hours. The disturbance is due to a high speed
solar wind stream associated with a well-positioned solar coronal
hole. The greater than 2 MeV electron flux was at high levels during
the past 24 hours.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be unsettled to slightly active for the next 24 hours.
The high speed wind stream is expected to slowly subside.
Predominantly unsettled levels should prevail during the second and
third days, but there will be a chance for isolated active periods,
especially at the higher latitudes.
