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 019 publicerat klockan 2200Z på 19 JAN 1998IA. Analys av solfläcksgrupper och solaktivitet från 18-2100Z till 19-2100Z SOLAR ACTIVITY WAS VERY LOW. A B3 FLARE AND WEAK TYPE
II SWEEP OCCURRED AT 19/0711Z. THE SOURCE REGION BECAME APPARENT
FROM SPACE-BASED IMAGERY WHICH INDICATED AN ERUPTION NEAR N28W81
FOLLOWED BY A CORONAL MASS EJECTION (CME). THE EVENT BEGAN LATE
YESTERDAY AS A DARK, BROAD SIX DEGREE LONG FILAMENT BECAME ACTIVE
THEN SLOWLY BEGAN LOSING MASS BEFORE FINALLY ERUPTING. REGION 8131
(S24W88) EXPERIENCED SEVERAL INTENSITY FLUCTUATIONS EARLY IN THE
PERIOD BUT IS NOW QUIETLY ROTATING AROUND THE WEST LIMB. NEW REGIONS
8140 (S14W61) AND 8141 (N26E48) WERE NUMBERED TODAY. THE REMAINING
REGIONS HAVE BEEN QUIET AND STABLE.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW.
IIA. Sammanfattning av geofysisk aktivitet 18-2100Z till 19-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET. MATERIAL FROM THIS MORNING'S CME APPEARED
WESTWARD DIRECTED SO NO EFFECTS ARE EXPECTED.
