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 054 publié à 2200Z le 23 FEB 2000IA. Analyse des régions solaires actives et activité du 22-2100Z au 23-2100Z SOLAR ACTIVITY WAS MODERATE DUE TO A SINGLE
UNCORRELATED M1 X-RAY FLARE AT 22/2147Z. THE FLARE WAS PROBABLY THE
SUPERPOSITION OF THREE EVENTS, A LONG DURATION C9 AND IMPULSIVE M1
AND C7 FLARES, BUT WITHOUT OPTICAL CORRELATION IT IS IMPOSSIBLE TO
BE SURE. THE REMAINDER OF THE PERIOD SAW NUMEROUS UNCORRELATED
C-CLASS FLARES AMIDST A BACKGROUND X-RAY FLUX AVERAGING NEARLY C2.
THREE NEW REGIONS WERE NUMBERED TODAY, 8884 (S11W74), 8885 (N11W43),
AND 8886 (S14E31).
IB. Prévisions d'activité solaire
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINANTLY LOW, WITH ISOLATED M-CLASS FLARES POSSIBLE. SOLAR
ACTIVITY IS EXPECTED TO BE ON THE RISE BY THE END OF THE PERIOD.
IMAGERY FROM THE YOHKOH SOFT X-RAY TELESCOPE SUGGESTS AT LEAST TWO
LARGE ACTIVE REGIONS WILL SOON BE ROTATING ONTO THE DISK.
IIA. Résumé de l'activité géophysique du 22-2100Z au 23-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. THE
FIELD INCREASED TO ACTIVE BETWEEN 15Z AND 18Z DUE TO THE ARRIVAL OF
A CO-ROTATING INTERACTION REGION (CIR) SEEN IN ACE DATA. THIS CIR
BROUGHT INCREASED SOLAR WIND VELOCITIES AND MAGNETIC FIELD STRENGTH;
BZ FLUCTUATED WILDLY BETWEEN -15 AND 10 NT. THE CIR HERALDS THE
EXPECTED RETURN OF A HIGH SPEED CORONAL HOLE STREAM.
IIB. Prévision de l'activité géophysique
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE IN THE MIDDLE LATITUDES AND
UNSETTLED TO MINOR STORM IN THE HIGHER LATITUDES FOR THE FIRST TWO
DAYS OF THE FORECAST PERIOD DUE TO THE EFFECTS OF A RECURRENT
CORONAL HOLE STREAM. ON THE THIRD DAY ACTIVITY IS EXPECTED TO
DIMINISH.
