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 333 publicerat klockan 2200Z på 28 NOV 1996IA. Analys av solfläcksgrupper och solaktivitet från 27-2100Z till 28-2100Z SOLAR ACTIVITY WAS LOW. REGION 7999 (S05W34)
PRODUCED A C1/SF AT 28/1243Z. THIS REGION DECAYED SLIGHTLY IN
BOTH SUNSPOT AREA AND NUMBER. ANOTHER LONG DURATION X-RAY
ENHANCEMENT OCCURRED BETWEEN 28/1535-1902Z. A C1 MAXIMUM WAS
REACHED. CORONAGRAPH DATA AFTER THE EVENT SHOWED A MASSIVE
CORONAL MASS EJECTION OFF THE WEST LIMB. THE LONGITUDES
BEHIND THE WEST LIMB MUST BE UNDERGOING SIGNIFICANT
EVOLUTION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS FORECAST TO BE
LOW. REGION 7999 IS CAPABLE OF PRODUCING OCCASIONAL C-CLASS
AND ISOLATED M-CLASS EVENTS.
IIA. Sammanfattning av geofysisk aktivitet 27-2100Z till 28-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. AT THE END OF
THE PERIOD, SOLAR WIND VELOCITIES WERE BELOW 450 KM/S.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD
SHOULD BE QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE
DAYS. THE CME MENTIONED ABOVE IS NOT EXPECTED TO RESULT IN
ANY DISTURBANCE. EVEN IF THE FLANK OF THE CME STRUCK THE
EARTH, THE EFFECTS WOULD BE MINIMAL.
