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 177 publicerat klockan 2200Z på 26 JUN 1998IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z SOLAR ACTIVITY WAS LOW. A C6/SF AT 25/2107Z FROM REGION
8253 (N17E26) WAS THE HIGHLIGHT OF AN OTHERWISE QUIET DAY. TWO NEW
REGIONS WERE NUMBERED, 8257 (N29W19) AND 8258 (S14E64), MAKING A
TOTAL OF SIX SPOTTED REGIONS ON THE DISK.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
THE GEOMAGNETIC FIELD WAS AT MAJOR TO SEVERE STORM LEVELS DURING THE
PAST 24 HOURS. A CORONAL MASS EJECTION WAS SEEN TO PASS THE ACE
SPACECRAFT BEGINNING AT APPROXIMATELY 25/1600Z. THE LATTER HALF OF
THE EVENT EXHIBITED STRONG, PROLONGED, SOUTHWARD MAGNETIC FIELDS
FROM 25/2200Z TO 26/0600Z. THE SOLAR SOURCE OF THIS EJECTA IS LIKELY
EITHER FROM ACTIVITY OCCURRING ON JUNE 20, OR JUNE 22. THE
DISTURBANCE WEAKENEND DURING THE SECOND HALF OF THE PERIOD, GIVING
WAY TO QUIET TO UNSETTLED CONDITIONS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PRIMARILY UNSETTLED, WITH PERIODS OF ACTIVE
CONDITIONS POSSIBLE DURING LOCAL NIGHTTIMES, FOR THE NEXT 24 HOURS.
QUIET TO UNSETTLED CONDITIONS SHOULD PREVAIL BY THE END OF THE
INTERVAL.
