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 086 publié à 2200Z le 27 Mar 2003IA. Analyse des régions solaires actives et activité du 26-2100Z au 27-2100Z Solar activity was at low levels. Region 322 (N19,
L=348) produced the two largest flares of the period, a C3.6 x-ray
flare at 27/0945Z and a C2.3 x-ray flare at 27/1455Z (both correlated
using SXI imagery). Region 321 (N05E34) has become a
beta-gamma-delta (weak) region which produced several low-level
flares during the period. Region 319 (N13W01) has shown rapid
development and has become a beta-gamma class group over the past 24
hours. Newly assigned Region 325 (N12E80-old Region 296) has begun
to rotate into view and was a large complex region on its previous
rotation. New Region 324 (S16E68) was also assigned today.
IB. Prévisions d'activité solaire
Solar activity is expected to be at
low levels. Regions 319 and 321 have the potential of producing
M-class flare activity
IIA. Résumé de l'activité géophysique du 26-2100Z au 27-2100Z
The geomagnetic field ranged from quiet to minor storm levels. The
Bz component of the interplanetary magnetic field ranged from +/- 10
nT throughout the period due to a recurrent high speed stream
(approximately 525 km/s at the time of this writing). The greater
than 2 MeV electron fluxes at geosynchronous orbit reached moderate
levels today.
IIB. Prévision de l'activité géophysique
The geomagnetic field is
expected to be at predominantly active levels. Minor storm
conditions are possible through day one of the interval due to a
favorably positioned recurrent coronal hole. Days two and three
should see a return to predominantly unsettled levels with
intermittent active conditions.
