Päikese aktiivsuse aruanne
Päikese ja geofüüsikalise aktiivsuse aruanne 2000 Feb 06 2200 UTCValminud NOAA © SWPC ja töödeldud SpaceWeatherLive.com-iga
Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 037 Välja antud 2200Z kuni 06 FEB 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 05-2100Z kuni 06-2100Z
SOLAR ACTIVITY WAS LOW. A C2/SF FLARE FROM REGION 8858
(N27E40) WAS THE LARGEST EVENT OF THE PERIOD. THIS REGION HAS BEEN
CONSIDERABLY MORE STABLE SINCE PRODUCING THE X1/3B MAJOR FLARE
YESTERDAY. SOME NEW SPOTS WERE DETECTED BUT OVERALL, THE COMPLEXITY
AND SIZE REMAINS THE SAME. SOME MINOR DEVELOPMENT WAS OBSERVED IN
REGION 8861 (N07W27), WHICH PRODUCED MINOR C-CLASS ACTIVITY LATE IN
THE PERIOD. OCCASIONAL MINOR C-CLASS EVENTS WERE ALSO DETECTED IN
REGION 8851 (N24W48). A PROMINENCE WAS OBSERVED ERUPTING OFF THE SE
LIMB AT 06/1650Z. NEW REGION 8862 (S04E75) WAS NUMBERED TODAY.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8858 RETAINS THE MOST POTENTIAL FOR M-CLASS
ACTIVITY. ISOLATED LOW C-CLASS FLARES ARE POSSIBLE FROM SEVERAL
SMALL REGIONS ON THE VISIBLE DISK.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 05/2100Z TO 06/2100Z:
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE WITH ISOLATED MINOR
STORMING PERIODS AT HIGH LATITUDES. THIS IS A CONTINUATION OF A
DISTURBANCE THAT BEGAN YESTERDAY IN RESPONSE TO A FAVORABLY
POSITIONED CORONAL HOLE.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO CONTINUE AT UNSETTLED TO ACTIVE LEVELS WITH MINOR
STORMING PERIODS LIKELY AT HIGH LATITUDES DURING LOCAL NIGHTTIME
HOURS. THE EFFECTS OF THIS CORONAL HOLE RELATED DISTURBANCE SHOULD
START SUBSIDING LATE ON DAY ONE. EXPECT MOSTLY QUIET TO UNSETTLED
CONDITIONS DURING DAYS TWO AND THREE. MATERIAL FROM YESTERDAY'S
IMPRESSIVE X1/3B CORONAL MASS EJECTION ALL APPEARED TO BE EASTWARD
BOUND FROM ITS SOURCE NEAR THE NE LIMB AND WILL LIKELY NOT EFFECT
EARTH.
