Rapport van de zonne- en geofysische activiteit van 1999 Jan 15 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 015 gepubliceerd omstreeks 2200Z op 15 JAN 1999IA. Analyse van de actieve zonneregio's en zonneactiviteit van 14-2100Z tot 15-2100Z
SOLAR ACTIVITY WAS MODERATE. REGION 8440 (N20E42)
CONTINUED AS THE DOMINANT ACTIVE REGION ON THE DISK AS IT PRODUCED
ANOTHER M-CLASS EVENT (M1/1F AT 0721Z), AS WELL AS NUMEROUS C-CLASS
FLARES. THE LARGEST C-CLASS EVENT WAS A C9/1B AT 1444Z. THE REGION
CONSISTS OF NEARLY 30 SPOTS, BRIGHT PLAGE, AND A POSSIBLE MIXED
POLARITY (DELTA) CONFIGURATION IN THE SOUTHERN PORTION OF THE
INTERMEDIATE SPOTS. REGION 8439 (S24E41) GENERATED A C3/1F AT 1314Z,
BUT LITTLE ELSE. IT HAS A SLIGHT DEGREE OF MAGNETIC COMPLEXITY AS
WELL AS APPROXIMATELY 25 SPOTS. ELSEWHERE, THE REMAINDER OF THE DISK
AND LIMBS WERE QUIET.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO REMAIN
MODERATE. CONTINUED M-CLASS FLARES ARE LIKELY FROM REGION 8440, AND
SHOULD FURTHER DEVELOPMENT OCCUR, REGION 8439.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 14/2100Z TO 15/2100Z:
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE AT MIDDLE LATITUDES, AND
UNSETTLED TO MINOR STORM AT HIGH LATITUDES. A HIGH-SPEED SOLAR WIND
STREAM HAS PROLONGED THE CME-RELATED DISTURBANCE THAT BEGAN ON 13
JANUARY. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS
ORBIT REACHED HIGH LEVELS AT APPROXIMATELY 1500Z.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PRIMARILY QUIET TO UNSETTLED THROUGHOUT THE PERIOD.
SUBSTORMS MAY BRING BRIEF ACTIVE LEVELS DURING LOCAL NIGHTTIMES OVER
THE NEXT 24 HOURS.
