Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 1999 Oct 19 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 292 gepubliceerd omstreeks 2200Z op 19 OCT 1999IA. Analyse van de actieve zonneregio's en zonneactiviteit van 18-2100Z tot 19-2100Z
SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT OF THE PERIOD
WAS A C8/SF FROM REGION 8732 (N22W52) AT 19/1941Z. THIS REGION
PRODUCED SEVERAL MINOR C-CLASS SUBFLARES THROUGHOUT THE PERIOD.
REGION 8731 (N13W45) HAS DECAYED SLIGHTLY , PRODUCING OCCASIONAL
MINOR SUBFLARES. AN EXTENDED PERIOD OF BRIGHT SURGING WAS OBSERVED
ON THE SE LIMB BETWEEN 19/0700 - 1000Z, A CME FROM THE SAME LOCATION
OCCURRED DURING THAT TIME FRAME. NEW REGION 8737 (S15E14) WAS
NUMBERED TODAY AND PRODUCED A SUBFLARE LATE IN THE PERIOD.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. THOUGH LARGE AND MAGNETICALLY COMPLEX REGION 8731 HAS
SHOWN SIGNS OF DECAY, IT MAINTAINS POTENTIAL FOR AN ISOLATED M-CLASS
EVENT. REGION 8732 IS EXPECTED TO CONTINUE PRODUCING C-CLASS
ACTIVITY. REGION 8737, IF IT MAINTAINS ITS PRESENT GROWTH RATE, WILL
SOON BECOME A GOOD CANDIDATE FOR C-CLASS ACTIVITY.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 18/2100Z TO 19/2100Z:
THE GEOMAGNETIC FIELD WAS AT QUIET TO UNSETTLED LEVELS WITH
OCCASIONAL ACTIVE PERIODS OBSERVED DURING LOCAL NIGHTTIME HOURS AT
HIGH LATITUDES. THE GREATER THAN TWO MEV ELECTRON FLUX REMAINED AT
MODERATE TO HIGH LEVELS.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN AT QUIET TO UNSETTLED LEVELS. OCCASIONAL ACTIVE
CONDITIONS ARE POSSIBLE ON DAYS TWO AND THREE AS A CORONAL HOLE
MOVES INTO A GEOEFFECTIVELY FAVORABLE POSITION.
