Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 2000 Jun 25 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 177 gepubliceerd omstreeks 2200Z op 25 JUN 2000IA. Analyse van de actieve zonneregio's en zonneactiviteit van 24-2100Z tot 25-2100Z
SOLAR ACTIVITY INCREASED TO MODERATE LEVELS DUE TO A
PAIR OF M-CLASS FLARES. THE FIRST WAS AN M2/SF AT 25/0114Z WITH AN
ASSOCIATED LOOP PROMINENCE SYSTEM FROM REGION 9042, NOW ABOUT A DAY
BEYOND THE WEST LIMB. THE SECOND WAS AN M1/2N AT 25/0752Z FROM
REGION 9046 (N21W61). THIS REGION SHOWED NO SIGNIFICANT CHANGES
DURING THE PERIOD AND REMAINED A SMALL, MIXED-POLARITY SPOT GROUP.
MINOR GROWTH WAS REPORTED IN REGIONS 9054 (N12W04) AND 9058
(S14W41). THE REMAINING REGIONS WERE STABLE AND SIMPLY-STRUCTURED.
AN ERUPTIVE PROMINENCE WAS OBSERVED AT NE26 AROUND 25/1200Z. NEW
REGION 9062 (S19E72) WAS NUMBERED.
IB. Voorspelling zonneactiviteit
ACTIVITY IS EXPECTED TO BE AT LOW TO
MODERATE LEVELS. ISOLATED M-CLASS FLARES ARE POSSIBLE DURING THE
PERIOD.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 24/2100Z TO 25/2100Z:
GEOMAGNETIC FIELD ACTIVITY DECREASED TO QUIET TO UNSETTLED LEVELS. A
GREATER THAN 10 MEV PROTON FLUX ENHANCEMENT AT GEOSYNCHRONOUS ORBIT
BEGAN AROUND 25/1300Z, LIKELY ASSOCIATED WITH THE M1/SF LIMB-FLARE
FROM OLD REGION 9042.
IIB. Voorspelling geofysische activiteit
GEOMAGNETIC FIELD ACTIVITY IS
EXPECTED TO INCREASE TO UNSETTLED TO ACTIVE LEVELS DURING 26 - 27
JUNE DUE TO CORONAL HOLE EFFECTS. BRIEF MINOR STORM CONDITIONS MAY
ALSO OCCUR DURING THIS PERIOD. FIELD ACTIVITY IS EXPECTED TO
DECREASE TO QUIET TO UNSETTLED LEVELS ON THE FINAL DAY OF THE
FORECAST PERIOD. THE GREATER THAN 10 MEV PROTON FLUX AT
GEOSYNCHRONOUS ORBIT IS EXPECTED TO RETURN TO BACKGROUND LEVELS
EARLY TOMORROW. THE GREATER THAN 2 MEV ELECTRON FLUX AT
GEOSYNCHRONOUS ORBIT IS EXPECTED TO REACH MODERATE TO HIGH LEVELS
LATE IN THE PERIOD.
