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 130 publié à 2200Z le 09 MAY 2000IA. Analyse des régions solaires actives et activité du 08-2100Z au 09-2100Z SOLAR ACTIVITY WAS LOW. REGION 8989 (N17E13) ENTERED A
GROWTH PHASE DURING THE PERIOD AND DEVELOPED MIXED MAGNETIC FIELDS
THAT MAY INCLUDE A WEAK DELTA CONFIGURATION. THIS REGION PRODUCED
NUMEROUS C-CLASS EVENTS. THE LARGEST WAS A C9/SN FLARE AT 09/1740Z.
SEVERAL LOW LEVEL C-CLASS EVENTS WERE OBSERVED FROM OTHER SMALL
REGIONS. EARLY IN THE PERIOD, ANOTHER LARGE CORONAL MASS EJECTION
BECAME VISIBLE IN THE LASCO CORONAGRAPH DATA. THIS SOUTHERN
HEMISPHERE EVENT APPEARS TO HAVE ORIGINATED FROM YET ANOTHER
FILAMENT ERUPTION IN THE SOUTH-CENTRAL PORTION OF THE SUN. A
MODERATE SIZE H TYPE SPOT ROTATED ONTO THE DISK AND WAS NUMBERED AS
REGION 8992 (N09E73).
IB. Prévisions d'activité solaire
SOLAR ACTIVITY SHOULD BE LOW TO
MODERATE. REGION 8989 IS CAPABLE OF PRODUCING OCCASIONAL SMALL
M-CLASS EVENTS. CONTINUED GROWTH HERE COULD RESULT IN THE
DISSOLUTION OF SEVERAL NEARBY FILAMENTS.
IIA. Résumé de l'activité géophysique du 08-2100Z au 09-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Prévision de l'activité géophysique
THE GEOMAGNETIC FIELD SHOULD
REMAIN QUIET TO UNSETTLED UNTIL MIDDAY ON 11 MAY WHEN A FILAMENT
ERUPTION RELATED STORM IS EXPECTED TO BEGIN. PREDOMINANTLY ACTIVE TO
MINOR STORM CONDITIONS ARE PREDICTED FROM THAT TIME THROUGH 13 MAY.
ISOLATED PERIODS OF MAJOR STORMING ARE POSSIBLE DURING THE
DISTURBANCE.
