Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 1999 Sep 02 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 245 gepubliceerd omstreeks 2200Z op 02 SEP 1999IA. Analyse van de actieve zonneregio's en zonneactiviteit van 01-2100Z tot 02-2100Z
SOLAR ACTIVITY HAS BEEN LOW FOR THE PAST 24 HOURS. MOST
OF THE 8 SPOTTED REGIONS DECLINED IN WHITE LIGHT AND MAGNETIC
COMPLEXITY. HOWEVER ONE REGION EMERGED RAPIDLY NEAR N10W06 AND WAS
NUMBERED AS REGION 8687. REGION 8675 (N19W41) PRODUCED A C6/2F LONG
DURATION FLARE THAT MAXED AT 1828 UT. A FILAMENT NEAR N25W05
DISAPPEARED BETWEEN 01/1923 AND 02/0720 UT. ANOTHER DARK FILAMENT
NEAR S30W15 DISAPPEARED BETWEEN 02/0720-1527 UT IN A PARTICULARLY
INTERESTING AREA OF EVOLVING LARGE-SCALE MAGNETIC FIELDS. AN
ERUPTIVE PROMINENCE THAT COULD BE SEEN OUT TO 0.49 SOLAR RADIUS WAS
OBSERVED ON THE SOUTHEAST LIMB (S27) NEAR 1400 UT.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE LOW
FOR THE NEXT THREE DAYS. REGIONS 8681 (N21W56) AND 8675 HAVE A SMALL
PROBABILITY OF ISOLATED M-CLASS X-RAY FLARES.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 01/2100Z TO 02/2100Z:
GEOMAGNETIC CONDITIONS HAVE RANGED BETWEEN QUIET AND ACTIVE FOR THE
LAST 24 HOURS. THE GEOMAGNETIC FIELD IS CONTINUING TO BE INFLUENCED
BY A STEADY, POSITIVE POLARITY (AWAY) SOLAR WIND STREAM OF MODERATE
SPEED (NEAR 450 KM/S). THE INTERPLANETARY MAGNETIC FIELD INTENSITY
WAS APPROXIMATELY 10 NT, AND WAS PREDOMINATELY SOUTHWARD,
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO PERSIST AT UNSETTLED TO OCCASIONALLY ACTIVE LEVELS
TOMORROW, DECREASING TOWARD GENERALLY UNSETTLED CONDITIONS BY THE
END OF THE FORECAST PERIOD. HOWEVER, DISTURBED SOLAR WIND FROM ANY
OF THE SEVERAL ERUPTIVE EVENTS OBSERVED TODAY MAY RAISE ACTIVITY TO
NEAR-STORM LEVELS ON SEPTEMBER 6 AND 7.
