Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 2000 Feb 07 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 038 gepubliceerd omstreeks 2200Z op 07 FEB 2000IA. Analyse van de actieve zonneregio's en zonneactiviteit van 06-2100Z tot 07-2100Z
SOLAR ACTIVITY WAS LOW. REGION 8861 (N08W40) PRODUCED
THE LARGEST EVENT OF THE PERIOD, A C4/SF AT 07/1654Z. THIS REGION
WAS ACTIVE THE ENTIRE PERIOD WITH FREQUENT PLAGE FLUCTUATIONS AND
SMALL C-CLASS FLARES. WHITE LIGHT GROWTH WAS ALSO IMPRESSIVE,
DEVELOPING FROM 20 MILLIONTHS YESTERDAY TO OVER 200 MILLIONTHS
TODAY. SOME MAGNETIC COMPLEXITY IS ALSO EVIDENT. REGION 8858
(N27E27) WAS ONCE AGAIN RELATIVELY STABLE, PRODUCING ONLY MINOR
C-CLASS ACTIVITY SINCE THE X1/3B FLARE ON 5 FEB. MODERATE MAGNETIC
COMPLEXITY STILL EXISTS BUT LOOKS LESS IMPRESSIVE THAN ANYTIME IN
THE PAST 48 HOURS. NO SIGNIFICANT ACTIVITY NOTED IN THE REMAINING
REGIONS.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 8858 AND 8861 BOTH HAVE POTENTIAL FOR M-CLASS
ACTIVITY.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 06/2100Z TO 07/2100Z:
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE WITH ISOLATED MINOR
STORMING PERIODS AT HIGH LATITUDES. THIS IS A CONTINUATION OF A
DISTURBANCE THAT BEGAN ON 5 FEB IN RESPONSE TO A FAVORABLY
POSITIONED CORONAL HOLE. THE GREATER THAN 2 MEV ELECTRON FLUX AT
GEOSYNCHRONOUS ORBIT WAS AT MODERATE TO HIGH LEVELS.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD WILL BE
UNSETTLED TO ACTIVE WITH OCCASIONAL MINOR STORMING PERIODS AT HIGH
LATITUDES DURING LOCAL NIGHTTIME HOURS. SOLAR WIND DATA INDICATE
THAT THIS DISTURBANCE SHOULD START SUBSIDING SOON. EXPECT MOSTLY
QUIET TO UNSETTLED CONDITIONS ON DAYS TWO AND THREE.
