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 332 publicerat klockan 2200Z på 27 NOV 1996IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z SOLAR ACTIVITY WAS VERY LOW. A VERY LONG DURATION
B9 X-RAY EVENT OCCURRED BETWEEN 26/2048-27/0456Z. OPTICAL
OBSERVATORIES OBSERVED BRIGHT KNOTS OF MATERIAL FLOWING ABOVE
THE WEST LIMB NEAR N05 WHERE REGION 7997 IS LOCATED. SPACE-BASED
CORONAGRAPH IMAGES NEAR THE PEAK OF THE EVENT SHOWED A LARGE
(GREATER THAN 1 SOLAR DIAMETER) CORONAL MASS EJECTION OVER THE
WEST LIMB. YOHKOH X-RAY IMAGES IN THE DECAY OF THE EVENT SHOWED
A LARGE, POST-CME ARCADE IN THAT LOCATION. REGION 7999 (S05W21)
WAS STABLE AND WEAK MIXED POLARITIES REMAINED IN THE CENTER OF
THE REGION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS FORECAST TO
BE LOW. REGION 7999 RETAINS THE CAPABILITY OF PRODUCING
C-CLASS AND ISOLATED M-CLASS EVENTS.
IIA. Sammanfattning av geofysisk aktivitet 26-2100Z till 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. ISOLATED ACTIVE
CONDITIONS WERE EXPERIENCED IN THE 27/0300-0600Z PERIOD.
SOLAR WIND DATA SHOW A MODERATELY HIGH VELOCITY (500-575
KM/S) STREAM IN THE EARTH'S VICINITY.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
FORECAST TO BE QUIET TO SLIGHTLY UNSETTLED FOR THE NEXT THREE
DAYS. THE CORONAL MASS EJECTION MENTIONED ABOVE IS NOT
EXPECTED TO IMPACT THE EARTH.
