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 065 publié à 2200Z le 05 Mar 2012IA. Analyse des régions solaires actives et activité du 04-2100Z au 05-2100Z Solar activity has been high. An X1/2b flare occurred
at 05/0409Z from Region 1429 (N17E41). This flare was associated
with a full halo CME with a LASCO C3 plane of sky speed of about
1340 km/sec. Region 1429 has a beta-delta magnetic class with an
area of approximately 810 millionths, and appears to be growing. The
region produced additional M-class flares during the period. New
Region 1431 (S27W36) was numbered today and is a small B-type
sunspot group.
IB. Prévisions d'activité solaire
Solar activity is expected to be
moderate, but there is a chance for additional major flare activity
and/or a greater than 10 MeV proton event from Region 1429.
IIA. Résumé de l'activité géophysique du 04-2100Z au 05-2100Z
The geomagnetic field has been mostly quiet to unsettled with the
exception of some active to minor storm periods at high latitudes. A
greater than 10 MeV proton flux enhancement began at about 05/0030Z.
Flux levels remained elevated throughout the day and reached a peak
of 3.9 pfu at 05/1630Z. The initial increase was associated with the
long duration M2 flare of 04 March, but additional particles were
also contributed by todays X1/CME event. The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels during the
period.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be unsettled to active for day 1 (06 Mar) due to
combined effects from the M4/CME event observed on 04 March and a
favorably positioned coronal hole high speed stream. Active
conditions with a chance for minor storm periods are forecast for
the second day (07 Mar) due to a expected glancing blow from todays
X1/full halo CME. Predominantly unsettled levels are expected for
the third day (08 Mar).
