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 293 publicerat klockan 2200Z på 19 OCT 1996IA. Analys av solfläcksgrupper och solaktivitet från 18-2100Z till 19-2100Z SOLAR ACTIVITY REMAINED VERY LOW. HOWEVER, A LARGE
FILAMENT LOCATED BETWEEN S28E61-S33E80 BEGAN TO DISAPPEAR NEAR
19/1600Z. THIS FILAMENT BECAME AN ERUPTIVE PROMINENCE AS IT
CONTINUED OUT BEYOND THE LIMB NEAR S28 TO A MAXIMUM HEIGHT OF
0.4R BEFORE FADING IN H-ALPHA. A LONG DURATION SOFT X-RAY
ENHANCEMENT BEGAN NEAR 19/1625Z AND REACHED A MAXIMUM OF A6
AT 19/1738Z. THE DECAY OF THIS X-RAY EVENT CONTINUES AT ISSUE
TIME. IT IS CERTAIN THIS EVENT REPRESENTS A LARGE CORONAL MASS
EJECTION. A NEW SMALL REGION IS APPEARING AT APPROXIMATELY
N15E90 IN RECENT YOHKOH IMAGES.
IB. Prognos för solaktivitet
SOLAR FLARE ACTIVITY SHOULD
CONTINUE AT A VERY LOW LEVEL FOR THE NEXT THREE DAYS.
IIA. Sammanfattning av geofysisk aktivitet 18-2100Z till 19-2100Z
THE GEOMAGNETIC FIELD RANGED BETWEEN UNSETTLED AND MINOR
STORM LEVELS DURING THE PERIOD AS THE CORONAL HOLE RELATED
DISTURBANCE CONTINUED. SOME HIGH LATITUDE SITES EXPERIENCED
PERIODS OF MAJOR STORMING. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT WERE MODERATE TO HIGH.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD
SHOULD REMAIN AT UNSETTLED TO MINOR STORM LEVELS FOR 20 OCT
AND EARLY 21 OCT. UNSETTLED TO SLIGHTLY ACTIVE CONDITIONS
SHOULD BE EXPERIENCED FOR THE LATTER HALF OF 21 OCT AND
THROUGH 22 OCT. THE PROBABLE CME MENTIONED ABOVE IS NOT
EXPECTED TO IMPACT THE EARTH DUE TO ITS MODERATELY HIGH
LATITUDE, NEAR EAST LIMB LOCATION, AND APPARENT TRAJECTORY
OUT OF THE ECLIPTIC PLANE.
