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 276 publié à 2200Z le 03 Oct 2001IA. Analyse des régions solaires actives et activité du 02-2100Z au 03-2100Z Solar activity was low with Region 9632 rotating beyond
the west limb today. Region 9648 (S05E64) produced the largest
flare during the period, a C8/SF at 02/0101 UTC. Region 9636
(N13W56) produced C6/SF occurring at 03/0643 UTC with an associated
Type II radio sweep with an estimated shock velocity of 558 km/s. A
C-class flare was recorded coming from Region 9645 (S18W27) and an
optical flare was also seen coming from Region 9634 (N11W63). Two
new regions were numbered today, 9649 (S06E70) and 9650 (S12E72).
IB. Prévisions d'activité solaire
Solar activity is forecast to be
moderate. Region 9636 is capable of producing M-class flares. Old
Region 9608 is returning on the southeast limb. It has a history of
producing M-class activity as well.
IIA. Résumé de l'activité géophysique du 02-2100Z au 03-2100Z
The geomagnetic field was at active to major storm levels. A CME
passage resulting from the M9 flare and associated activity on the
southwest limb early on the 1st is suspected of being the source.
The greater than 10 MeV proton flux peaked at 02/0810 UTC, 2360 pfu.
Flux levels remained above event level at time of bulletin issue.
IIB. Prévision de l'activité géophysique
Geomagnetic activity is
expected to be at unsettled to minor storm levels during the first
day as CME effects subside. Quiet to unsettled conditions should
prevail on the last two days of period. The greater than 10 MeV
proton event is expected to end during day one of the forecast
period.
