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 212 publicerat klockan 2200Z på 30 JUL 2000IA. Analys av solfläcksgrupper och solaktivitet från 29-2100Z till 30-2100Z SOLAR ACTIVITY HAS BEEN LOW. THE LARGEST EVENT OF THE
DAY WAS AN OPTICALLY UNCORRELATED C7 FLARE AT 30/1210Z. SOHO/EIT
IMAGERY SUGGESTS REGION 9107 (S18E56) AS THE LIKELY SOURCE. A C4/SF
FLARE WAS OBSERVED IN REGION 9105 (N16E40) AT 30/1314Z, AND REGION
9103 (N11W26) PRODUCED SEVERAL SUBFAINT FLARES WITHOUT NOTABLE X-RAY
ENHANCEMENT. SOME SMALLER C-CLASS FLARES WERE ALSO OBSERVED DURING
THE DAY, BUT WITHOUT OPTICAL CORRELATION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO PERSIST
AT THE LOW LEVEL FOR THE NEXT THREE DAYS, WITH A SLIGHT INCREASE IN
CHANCES FOR ISOLATED MODERATE-LEVEL ACTIVITY BY THE THIRD DAY DUE TO
RETURNING REGIONS EXPECTED ON THE EAST LIMB.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 29/2100Z TO 30/2100Z:
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED, WITH ISOLATED
ACTIVE PERIODS OF LOCAL SUBSTORMING OBSERVED IN THE NIGHTTIME
SECTOR.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY QUIET TO UNSETTLED, WITH A GREATER
CHANCE OF ACTIVE PERIODS AND ISOLATED MINOR STORMING AT HIGHER
LATITUDES FROM INFLUENCE OF CORONAL HOLES EXPECTED ON DAY TWO AND
THREE.
