Activiteitenrapport
Rapport van de zonne- en geofysische activiteit van 2000 Jun 08 2200 UTCOpgemaakt door de NOAA © SWPC en verwerkt door Poollicht.be
USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 160 gepubliceerd omstreeks 2200Z op 08 JUN 2000IA. Analyse van de actieve zonneregio's en zonneactiviteit van 07-2100Z tot 08-2100Z
SOLAR ACTIVITY WAS LOW. NUMEROUS MINOR C-CLASS X-RAY
EVENTS OCCURRED. TWO EVENTS WERE OPTICALLY CORRELATED WITH REGION
9026 (N21W17). ONLY ONE C1/SF EVENT WAS OPTICALLY CORRELATED WITH
REGION 9033 (N22E42) AT 08/1811Z. REGION 9026 SHOWED A MODERATE
INCREASE IN THE NUMBER OF SPOTS WHILE THE AREA SLIGHTLY DECREASED,
AND THE MAGNETIC CONFIGURATION OF THE REGION BECAME BETA GAMMA.
OVERALL, IT APPEARS 9026 IS STARTING TO DECAY. SIGNIFICANT GROWTH
WAS OBSERVED IN REGION 9033. NEW REGIONS 9035 (S17E15) AND 9036
(S23E73) WERE NUMBERED TODAY.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE
MODERATE TO HIGH. REGION 9026 AND 9033 ARE EACH CAPABLE OF
PRODUCING M-CLASS AND ISOLATED X-CLASS EVENTS.
IIA. GEOPHYSICAL ACTIVITY SUMMARY FROM 07/2100Z TO 08/2100Z:
THE GEOMAGNETIC FIELD WAS UNSETTLED TO SEVERE STORM. A SUDDEN
IMPULSE OCCURRED AT 08/0909Z (77 NT, AS MEASURED BY THE BOULDER USGS
MAGNETOMETER). THE SOLAR WIND VELOCITY JUMPED FROM 520 TO OVER 800
KM/S AT 08/0841Z. MINOR TO SEVERE STORM LEVELS WERE OBSERVED
FOLLOWING THE SHOCK ARRIVAL. THIS SHOCK IS PRESUMED TO BE RELATED
TO THE X2/3B EVENT ON 06 JUNE. THE GREATER THAN 10 MEV PROTON FLUX
AT GEOSYNCHRONOUS ORBIT PEAKED AT 84 PFU'S AT 08/0940Z AND IS
DECREASING AT THIS TIME. A MODERATE (7.4 PERCENT) FORBUSH DECREASE
PEAKED NEAR 08/1449Z. A MAGNETOPAUSE CROSSING WAS OBSERVED ON
GOES-8 (W075) BEGAN AT 08/1510Z AND CONTINUED UNTIL APPROXIMATELY
08/1615Z.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO RANGE FROM ACTIVE TO SEVERE STORM LEVELS DURING THE
FIRST DAY. GEOMAGNETIC STORMING SHOULD START TO DIMINISH DURING THE
MIDDLE OF THE PERIOD. CONDITIONS BY THE THIRD DAY ARE EXPECTED TO
BE QUIET TO UNSETTLED WITH ISOLATED PERIODS OF ACTIVE CONDITIONS.
HOWEVER, UNSETTLED TO MINOR STORM CONDITIONS MAY PERSIST DURING THE
LATER PART OF THE PERIOD IF MODERATE EFFECTS ARE OBSERVED FROM THE
X1/3B EVENT ON 7 JUNE.
