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 153 publicerat klockan 2200Z på 02 JUN 1998IA. Analys av solfläcksgrupper och solaktivitet från 01-2100Z till 02-2100Z SOLAR ACTIVITY REMAINED VERY LOW. ONLY SMALL B-CLASS
ENHANCEMENTS WERE OBSERVED. REGION 8230 (S19E24) GREW AT A MODERATE
PACE. NEW REGION 8232 (S19E74) ROTATED ONTO THE DISK. A MODERATE
SIZE CLASS H SPOT WAS VISIBLE HERE AND TRAILER SPOTS MAY FOLLOW.
THIS REGION IS THE RETURN OF OLD REGION 8213 THAT PRODUCED SEVERAL
C-CLASS FLARES AND ONE M-CLASS FLARE LAST ROTATION. A LARGE
PROMINENCE NEAR SW50 ERUPTED SHORTLY BEFORE 02/1500Z AND CREATED A
LARGE AND DENSE CORONAL MASS EJECTION THAT APPEARED TO PROPAGATE
SLIGHTLY OUT OF THE ECLIPTIC PLANE.
IB. Prognos för solaktivitet
SOLAR ACTIVITY SHOULD BECOME LOW.
REGION 8230 SHOULD BEGIN TO PRODUCE ISOLATED C-CLASS EVENTS DURING
THIS GROWTH PHASE. NEW REGION 8232 IS EXPECTED TO GENERATE
OCCASIONAL C-CLASS EVENTS AND POSSIBLY AN ISOLATED M-CLASS FLARE.
LIMB PROXIMITY OF THIS REGION HINDERS ACCURATE ANALYSIS.
IIA. Sammanfattning av geofysisk aktivitet 01-2100Z till 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. ENERGETIC ELECTRON
FLUXES AT GEOSYNCHRONOUS ORBIT BEGAN THE PERIOD AT HIGH LEVELS BUT
DECREASED QUICKLY TO MODERATE LEVELS FOR THE REMAINDER OF THE
PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS.
