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 340 publicerat klockan 2200Z på 06 DEC 1997IA. Analys av solfläcksgrupper och solaktivitet från 05-2100Z till 06-2100Z SOLAR ACTIVITY WAS LOW. TWO UNCORRELATED C1 XRAY BURSTS
WERE DETECTED. REGION 8113 (N21W55) CONTINUED TO DECAY AS IT NEARED
THE WEST LIMB. THIS REGION IS NOW CLASSIFIED AS A CAO GROUP OF 7
SPOTS IN A SIMPLE MAGNETIC CONFIGURATION. REGION 8115 (N33W34)
SHOWED LITTLE CHANGE FROM YESTERDAY. REGION 8116 (N26E27) DISPLAYED
SLIGHT GROWTH AND IS NOW CLASSIFIED AS A CRO GROUP OF ONLY 4 SPOTS.
ALL REGIONS WERE RELATIVELY QUIET. THE LARGE FILAMENT STRUCTURE IN
THE NORTHWEST QUADRANT OF THE VISIBLE DISK LOST CONSIDERABLE MASS
OVER THE PAST 24 HOURS BUT PRODUCED LITTLE IN THE WAY OF A CORONAL
MASS EJECTION SIGNATURE.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW FOR THE ENTIRE FORECAST PERIOD. REGION 8113 STILL HAS THE
POTENTIAL FOR C-CLASS FLARING AND AN OUTSIDE CHANCE OF ISOLATED
MINOR M-CLASS ACTIVITY AS IT FURTHER DECAYS.
IIA. Sammanfattning av geofysisk aktivitet 05-2100Z till 06-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET AT ALL LATITUDES WITH ISOLATED PERIODS OF
UNSETTLED LEVELS FOR THE ENTIRE FORECAST PERIOD.
