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 063 publié à 2200Z le 04 Mar 2003IA. Analyse des régions solaires actives et activité du 03-2100Z au 04-2100Z Solar activity was low. A long duration C2 flare
occurred at 03/2105Z from a spotless plage field near S27E72. A
large coronal mass ejection off the SE limb was observed on
coronagraph imagery following this flare. There have been no white
light developments near the source region in the past 24 hours and
no other significant activity was noted. Region 296 (N11E21) remains
the largest sunspot group on the visible disk and now measures
approximately 650 millionths in a beta-gamma magnetic configuration.
Despite the size and complexity of this region, it has been rather
quiet with just occasional plage fluctuations and minor surges
observed. New Regions 301 (N21E36) and 302 (N19E62) were numbered
today.
IB. Prévisions d'activité solaire
Solar activity is expected to continue
at low levels. Isolated C-class flares are possible primarily from
Region 296, with a slight chance of a low M-class flare.
IIA. Résumé de l'activité géophysique du 03-2100Z au 04-2100Z
The geomagnetic field was unsettled to active with isolated minor
storm periods at high latitudes. This disturbance is due to a high
speed coronal hole stream that began late in the day yesterday.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to continue at unsettled to active levels early, but will
return to quiet to unsettled levels late on day one as the high
speed stream subsides. Isolated active periods at mostly higher
latitudes are possible through the next three days.
