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 066 publié à 2200Z le 06 Mar 2004IA. Analyse des régions solaires actives et activité du 05-2100Z au 06-2100Z Solar activity increased to moderate levels today.
Region 570 (S13E70) produced an M1 x-ray flare at 06/1217Z.
Multiple lesser C-class flares were also observed throughout the
day. A cluster of trailing sunspots became visible early in the
period. There is a significant distance between the lead and
trailing sunspots (over 15 heliospheric degrees) although initial
magnetic analysis suggest that all features associated to plague
field are one region. Region 567 (S12W55) produced two low level
C-class flares early in the period. The sunspot coverage increased
since yesterday although the weak delta complex separated into two
distinct sunspots today, indicating some decay in magnetic field
structure. No new regions were numbered today.
IB. Prévisions d'activité solaire
Solar activity is expected to be at
low to moderate levels.
IIA. Résumé de l'activité géophysique du 05-2100Z au 06-2100Z
The geomagnetic field was at quiet to unsettled levels. The greater
than 2 MeV electron fluxes at geosynchronous orbit reached high
levels today.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be quiet to unsettled through 7 and 8 March. The onset
of an intense solar sector boundary crossing is anticipated on 9
March, which precedes a recurrent high speed coronal hole stream.
Active to minor storm conditions are expected with the onset.
