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 066 publié à 2200Z le 06 MAR 2000IA. Analyse des régions solaires actives et activité du 05-2100Z au 06-2100Z SOLAR ACTIVITY HAS BEEN LOW FOR THE PAST 24 HOURS.
TODAY'S LARGEST EVENT WAS AN OPTICALLY UNCORRELATED C4 FLARE AT
1049Z. REGION 8891 (S16W58) IS DECLINING SLOWLY BUT CONTINUES TO BE
THE LARGEST GROUP ON THE DISK. REGION 8898 (S13E20) CONTINUED TO
GROW AND SHOWED OCCASIONAL BRIGHTENINGS AND SUBFLARE ACTIVITY.
REGION 8900 (S15W12) IS ALSO GROWING, BUT WAS QUIETER THAN 8898.
REGION 8889 (N19W74), WHICH HAS BEEN VERY STABLE OVER THE LAST FEW
DAYS, PRODUCED A C3/SF AT 1619Z WHICH WAS ACCOMPANIED BY A BRIGHT
SURGE ON THE LIMB. SOHO/EIT IMAGES SHOWED THE ERUPTION OF A FILAMENT
IN THE NORTHWEST PART OF THE DISK ON THE 5TH AROUND 1700Z.
CORONAGRAPH DATA SHOW THAT THE CME MATERIAL IS NOT DIRECTED TOWARDS
THE EARTH.
IB. Prévisions d'activité solaire
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. THERE IS A FAIR CHANCE FOR AN ISOLATED M-CLASS EVENT
OVER THE NEXT THREE DAYS FROM REGION 8891, 8898, OR 8900.
IIA. Résumé de l'activité géophysique du 05-2100Z au 06-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. A SOLAR SECTOR BOUNDARY
CROSSING WAS OBSERVED AT THE ACE SPACECRAFT AT 06/0200Z. SINCE THAT
TIME, SPEEDS HAVE BEEN SLIGHTLY ELEVATED AND THE GEOMAGNETIC FIELD
HAS BEEN MOSTLY UNSETTLED.
IIB. Prévision de l'activité géophysique
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS.
