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 226 publicerat klockan 2200Z på 14 AUG 1997IA. Analys av solfläcksgrupper och solaktivitet från 13-2100Z till 14-2100Z SOLAR ACTIVITY WAS LOW. REGION 8071 (N26W22) PRODUCED A
C1/SF FLARE AT 0132Z. THERE HAVE NOT BEEN ANY FLARES SINCE THIS
EVENT AND THE REGIONS ON THE DISK APPEAR TO BE STABLE. STACKED
REGIONS 8073 (N14E36) AND 8074 (N26E38) CURRENTLY SHARE A NEUTRAL
LINE BETWEEN 8073'S TRAILER AND 8074'S LEADER, BUT THE FIELDS ARE
RATHER WEAK, AND THIS AREA DOES NOT CURRENTLY POSE A SIGNIFICANT
FLARE THREAT.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW. THERE IS A SLIGHT CHANCE FOR AN ISOLATED C-CLASS EVENT.
IIA. Sammanfattning av geofysisk aktivitet 13-2100Z till 14-2100Z
THE GEOMAGNETIC FIELD RANGED FROM QUIET TO MAJOR STORM LEVELS OVER
THE PAST 24 HOURS. AN INITALLY UNSETTLED FIELD BECAME INCREASINGLY
DISTURBED BETWEEN 0400-0900Z: MIDDLE LATITUDES WERE MOSTLY ACTIVE
AND HIGH LATITUDES SHOWED A RANGE OF LEVELS FROM ACTIVE TO MAJOR
STORM. SINCE 0900Z, CONDITIONS HAVE BEEN MOSTLY QUIET WITH THE
EXCEPTION OF OCCASIONAL UNSETTLED PERIODS.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PREDOMINANTLY UNSETTLED FOR THE NEXT 24 HOURS, AND
UNSETTLED TO QUIET FOR THE SECOND AND THIRD DAYS. THERE IS A CHANCE
FOR SOME ACTIVE LEVEL DISTURBANCES DURING LOCAL NIGHTTIME HOURS.
