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 160 publicerat klockan 2200Z på 09 JUN 1998IA. Analys av solfläcksgrupper och solaktivitet från 08-2100Z till 09-2100Z SOLAR ACTIVITY WAS VERY LOW. ALL VISIBLE REGIONS
APPEARED STABLE OR DECLINING. TWO SMALL SPOT GROUPS WERE NUMBERED
TODAY, REGION 8240 (S24W44) AND REGION 8241 (S27E17). A PARTIAL
HALO CME WAS OBSERVED AT 09/0627UT. MATERIAL WAS SEEN MOVING MOSTLY
TO THE SW. THIS EVENT MAY BE ASSOCIATED WITH DISAPPEARING FILAMENTS
ALONG THE SOUTHERN POLAR CROWN DURING THIS PERIOD.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW TO VERY LOW EARLY IN THE PERIOD. LEVELS MAY INCREASE ON 12 JUN
WHEN OLD REGION 8226 (N12, L-210) IS DUE TO RETURN. REGION 8226
APPEARED TO BE GROWING AND PRODUCED MAJOR FLARES AS IT CROSSED WEST
LIMB ON 29 MAY.
IIA. Sammanfattning av geofysisk aktivitet 08-2100Z till 09-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2MEV
ELECTRON FLUX HAS BEEN AT MODERATE LEVELS FOR MOST OF THE DAY.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED. ISOLATED ACTIVE PERIODS ARE
POSSIBLE, ESPECIALLY ON 12 JUN IN RESPONSE TO THE CME OBSERVED ON 8
JUN.
