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 317 publicerat klockan 2200Z på 13 NOV 1997IA. Analys av solfläcksgrupper och solaktivitet från 12-2100Z till 13-2100Z SOLAR ACTIVITY HAS BEEN LOW. A SERIES OF UNCORRELATED
C-CLASS X-RAY BURSTS HAVE BEEN DETECTED OVER THE PAST 24 HOURS, THE
LARGEST OF WHICH WAS A C2.3 AT 13/1508Z. REGION 8106 (N28W71)
PRODUCED A C1/SF WITH AN ASSOCIATED HIGH SPEED SURGE AT 13/1746Z.
THIS REGION CONTINUES TO GROW SLOWLY AS IT NEARS THE WEST LIMB. NEW
REGIONS 8107 (S25W26), A DRO SPOT GROUP, AND 8108 (N21E78), AN HAX
SPOT GROUP, WERE NUMBERED TODAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW. REGION 8108 EXHIBITS SPORADIC SURGING AND BRIGHTENING AND
APPEARS TO HAVE FAIR TO GOOD FLARE AND GROWTH POTENTIAL AS IT
ROTATES ONTO THE VISIBLE DISK. THIS REGION MAY DEVELOP A FAIR CHANCE
OF M-CLASS FLARE PRODUCTION OVER THE NEXT FEW DAYS.
IIA. Sammanfattning av geofysisk aktivitet 12-2100Z till 13-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET FOR THE ENTIRE FORECAST PERIOD. HIGH
LATITUDES MAY EXPERIENCE SOME INTERMITTENT PERIODS OF UNSETTLED
ACTIVITY.
