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 307 publicerat klockan 2200Z på 03 NOV 1999IA. Analys av solfläcksgrupper och solaktivitet från 02-2100Z till 03-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. THERE HAVE
BEEN ONLY MINOR X-RAY ENHANCEMENTS IN THE PAST 24 HOURS. TWO SMALL
SPOT GROUPS WERE NUMBERED TODAY, 8752 (S12E01) AND 8753 (N21 E63).
EXCEPT FOR SOME MINOR MAGNETIC COMPLEXITY IN REGION 8749 (S18W26)
ALL REGIONS ARE STABLE OR DECLINING. THE LARGE EQUATORIAL CORONAL
HOLE WHICH CROSSED CM ON 11 OCT HAS FULLY ROTATED ON TO THE DISK AND
IN SOME WAVELENGTHS APPEARS TO EXTEND TO THE CENTRAL MERIDIAN.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO VERY LOW. THE ACTIVE LONGITUDES OF THE LAST SOLAR ROTATION WILL
ROTATE INTO VIEW OVER THE NEXT FEW DAYS, HOWEVER, THERE IS CURRENTLY
NO EVIDENCE OF ANY STRONG ACTIVITY IN THIS AREA.
IIA. Sammanfattning av geofysisk aktivitet 02-2100Z till 03-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED EARLY IN THE PERIOD. ACTIVITY IS
EXPECTED TO BEGIN TO INCREASE LATE IN THE PERIOD AS A CONSEQUENCE OF
THE LARGE EQUATORIAL CORONAL HOLE NOW APPROACHING CM.
