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 276 publicerat klockan 2200Z på 03 OCT 1999IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z SOLAR ACTIVITY CONTINUED AT A LOW LEVEL. REGION 8716
(N20E60) PRODUCED A LONG DURATION C3/SF AT 03/1545Z. SEVERAL REGIONS
RECENTLY ROTATED OVER THE NORTHEAST AND SOUTHEAST LIMBS. THE MOST
COMPLEX AREA APPEARS TO BE IN THE NORTHEAST WHERE REGIONS 8716 AND
NEW 8720 (N14E65) ARE LOCATED IN CLOSE PROXIMITY. IN THE SOUTHEAST,
NEW REGIONS 8719 (S20E50) AND 8721 (S17E56) ALSO APPEARED TO BE
ALMOST ABUTTED. HOWEVER, NO CURRENT DISK REGIONS SHOWED MUCH IN THE
WAY OF DYNAMICS AND NO ONE REGION SHOWED SIGNIFICANT MAGNETIC
COMPLEXITY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD REMAIN
PREDOMINANTLY LOW FOR THE NEXT THREE DAYS. AN ISOLATED M-CLASS EVENT
IS MILDLY POSSIBLE FROM THE REGION 8716/8720 COMPLEX.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. SOLAR WIND VELOCITY
DROPPED INTO THE 400 KM/S RANGE. ENERGETIC ELECTRON FLUXES REACHED
HIGH LEVELS DURING THE PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD BE
GENERALLY QUIET TO UNSETTLED FOR THE NEXT THREE DAYS. ISOLATED
ACTIVE PERIODS ARE POSSIBLE AT HIGH LATITUDES.
