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 320 publicerat klockan 2200Z på 16 NOV 1997IA. Analys av solfläcksgrupper och solaktivitet från 15-2100Z till 16-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8108 (N21E42)
PRODUCED AN M1/1N TENFLARE AT 15/2246Z. REGION 8108 ALSO PRODUCED A
SMALL C1/SF FLARE AT 16/0125Z. THIS REGION HAS DECREASED IN OVERALL
SIZE BUT HAS INCREASED ITS NUMBER OF SPOTS. IT IS NOW AN EAI SPOT
GROUP WITH A COMPLEX MAGNETIC CLASSIFICATION. TWO UNCORRELATED
C-CLASS X-RAY BURSTS WERE ALSO DETECTED AT THE END OF THE PERIOD.
NEW REGION 8109 (S18E66), A SINGLE HRX SPOT SO FAR, WAS NUMBERED
TODAY. THIS APPEARS TO BE RETURNING REGION 8101.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8108 HAS A GOOD CHANCE OF C-CLASS ACTIVITY AND A
CHANCE OF ISOLATED M-CLASS ACTIVITY.
IIA. Sammanfattning av geofysisk aktivitet 15-2100Z till 16-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED AT ALL LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED FOR THE NEXT 24 HOURS, THEN
BECOME MOSTLY UNSETTLED FOR THE REMAINDER OF THE FORECAST PERIOD.
HIGH LATITUDES MAY EXPERIENCE PERIODS OF ACTIVE LEVELS THROUGHOUT
THE FORECAST PERIOD. SLIGHTLY INCREASED ACTIVITY IS EXPECTED AS A
RESULT OF THE OBSERVED CORONAL MASS EJECTION OF THE EAST SOLAR LIMB
TWO DAYS AGO.
