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 014 publié à 2200Z le 14 Jan 2003IA. Analyse des régions solaires actives et activité du 13-2100Z au 14-2100Z Solar activity was low. Region 242 has now rotated
around the west limb near S07, but continues to be quite active. It
was the likely source of several small C-class flares and was
responsible for today's largest event, a C6 flare at 14/0636Z. The
largest region on the disk is Region 255 (S13W12). This region's
close proximity to Region 251 (S14W05) adds complexity, but activity
this period was limited to occasional fluctuations in the plage
field. A large prominence eruption off the SE limb was observed to
begin at around 14/1700Z. New Regions 258 (N07E56) and 259 (N13E72)
were numbered today. Limb proximity hinders a thorough analysis, but
limb activity was considerable over the past few days in the
vicinity of these newly numbered regions.
IB. Prévisions d'activité solaire
Solar activity is expected to continue
at low levels. There is a slight chance for a small M-class flare.
IIA. Résumé de l'activité géophysique du 13-2100Z au 14-2100Z
The geomagnetic field was quiet to unsettled with isolated active
periods at higher latitudes. A period (04-12Z) of mostly southward
orientation in the IMF was responsible for the more disturbed
periods.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to continue at quiet to unsettled levels. Isolated active
periods are likely at higher latitudes.
