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 314 publicerat klockan 2200Z på 10 NOV 1998IA. Analys av solfläcksgrupper och solaktivitet från 09-2100Z till 10-2100Z SOLAR ACTIVITY REMAINED MODERATE. REGION 8375 (N22W88)
PRODUCED AN M1/SF AT 10/1544Z WITH AN ASSOCIATED LOOP PROMINENCE
SYSTEM. THIS REGION PRODUCED SEVERAL LOW TO MID C-CLASS EVENTS
DURING THE PERIOD. REGION 8384 (S27E63) WAS RELATIVELY QUIET BUT
EXHIBITED MIXED POLARITIES AND A POSSIBLE DELTA CONFIGURATION. A
PARTIAL HALO CORONAL MASS EJECTION WAS OBSERVED BY SOHO/LASCO OVER
THE NORTHERN HEMISPHERE BEGINNING AT 09/1754Z. SEVERAL OTHER LARGE
MASS EJECTIONS WERE OBSERVED DURING THE PERIOD FROM THE NORTHWEST
AND SOUTHEAST LIMBS.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BE LOW TO
MODERATE FOR THE NEXT TWO DAYS. REGION 8375 SHOULD CONTINUE TO
PRODUCE FREQUENT C-CLASS AND OCCASIONAL M-CLASS EVENTS. X-CLASS
EVENTS FROM THIS REGION REMAIN POSSIBLE. ON 13 NOV, FLARE FREQUENCY
SHOULD DECREASE AS REGION 8375 ROTATES FAR BEYOND THE WEST LIMB.
REGION 8384 COULD BEGIN TO PRODUCE SMALL FLARES DUE TO ITS MAGNETIC
CONFIGURATION.
IIA. Sammanfattning av geofysisk aktivitet 09-2100Z till 10-2100Z
THE GEOMAGNETIC FIELD WAS PREDOMINANTLY QUIET TO UNSETTLED. BRIEF
ACTIVE CONDITIONS WERE OBSERVED AT HIGH LATITUDES EARLY IN THE
PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD
REMAIN QUIET TO UNSETTLED FOR 11-12 NOV. UNSETTLED TO ACTIVE LEVELS
ARE FORECAST FOR 13 NOV IN RESPONSE TO THE PARTIAL HALO MASS
EJECTION OBSERVED ON 09 NOV.
