USAF/NOAA rapport van de zonneactiviteit en geofysische activiteit
SDF Nummer 243 gepubliceerd omstreeks 2200Z op 30 AUG 2000IA. Analyse van de actieve zonneregio's en zonneactiviteit van 29-2100Z tot 30-2100Z
SOLAR ACTIVITY WAS LOW. TODAY'S MOST SIGNIFICANT X-RAY
EVENT WAS A LONG DURATION C4 EVENT FROM 29/2235Z TO 30/0028Z. THERE
WAS AN ASSOCIATED CME DIRECTED AWAY FROM THE SOUTHEAST LIMB WHICH
WAS OBSERVED TO ENTER THE C2 FIELD OF VIEW AT 29/2354Z AND THE C3
FIELD OF VIEW AT 30/0042Z. DISK ACTIVITY WAS APPARENT IN EIT IMAGES
BETWEEN REGIONS 9148 (S19E18) AND 9143 (S18W06). ADDITIONAL
LOW-LEVEL C-CLASS EVENTS WERE OBSERVED THROUGHOUT THE DAY. REGION
9149 (N11E44) IS CURRENTLY THE LARGEST GROUP ON THE DISK WITH AN
AREA OF 330 MILLIONTHS. THE GROUP APPEARS TO BE STABLE AT THIS TIME.
IB. Voorspelling zonneactiviteit
SOLAR ACTIVITY IS EXPECTED TO BE
MOSTLY LOW, BUT THERE IS A SLIGHT-TO-FAIR CHANCE FOR AN ISOLATED
M-CLASS EVENT DURING THE NEXT THREE DAYS.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 29/2100Z TO 30/2100Z:
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO ACTIVE LEVELS DURING THE
PAST 24 HOURS. REAL-TIME SOLAR WIND OBSERVATIONS FROM ACE INDICATE
THE CONTINUATION OF A HIGH-SPEED, POSITIVE-POLARITY, CORONAL HOLE
STREAM. THE FLOW SEEMS TO BE WEAKENING SLOWLY AS EVIDENCED BY A
GRADUAL DECLINE IN THE VELOCITY. THE GREATER THAN 2 MEV ELECTRON
FLUX AT GEOSYNCHRONOUS ORBIT WAS HIGH (GREATER THAN 1000 PFU) DURING
THE PAST 24 HOURS.
IIB. Voorspelling geofysische activiteit
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY UNSETTLED DURING THE NEXT THREE DAYS.
