Solaktivitetsrapport
Any mentioned solar flare in this report has a scaling factor applied by the Space Weather Prediction Center (SWPC). Because of the SWPC scaling factor, solar flares are reported as 42% smaller than for the science quality data. The scaling factor has been removed from our archived solar flare data to reflect the true physical units.

USAF/NOAA rapport för sol- och geofysisk aktivitet
SDF Nummer 213 publicerat klockan 2200Z på 31 JUL 2000IA. Analys av solfläcksgrupper och solaktivitet från 30-2100Z till 31-2100Z SOLAR ACTIVITY HAS BEEN LOW. SEVERAL OPTICALLY
UNCORRELATED MINOR C-CLASS EVENTS WERE OBSERVED. THE LARGEST WAS A
C3 OBSERVED AT 31/0206Z. REGION 9107 WAS SPLIT INTO TWO REGIONS
TODAY: REGION 9107 (S16E38), AND NEW REGION 9110 (S19E55), WITH
BETA MAGNETIC CLASSIFICATION AND DSO AND ESO SPOT CLASSIFICATIONS,
RESPECTIVELY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO PERSIST
AT A LOW LEVEL FOR THE FIRST TWO DAYS, WITH A GREATER CHANCE OF
MODERATE ACTIVITY BY DAY THREE DUE TO ROTATION OF ACTIVE REGIONS
AROUND THE EAST LIMB.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 30/2100Z TO 31/2100Z:
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO ACTIVE, WITH ISOLATED ACTIVE
PERIODS OBSERVED IN THE LOCAL NIGHTTIME SECTOR AT MIDDLE AND HIGH
LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT TWO DAYS, WITH
ACTIVE PERIODS DUE TO POSSIBLE INFLUENCE OF A FAVORABLY POSITIONED
CORONAL HOLE. QUIET TO UNSETTLED CONDITIONS ARE MORE LIKELY BY DAY
THREE.
