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 207 publicerat klockan 2200Z på 26 JUL 1997IA. Analys av solfläcksgrupper och solaktivitet från 25-2100Z till 26-2100Z SOLAR ACTIVITY WAS VERY LOW. ONLY A FEW B-CLASS EVENTS
WERE OBSERVED DURING THE PERIOD. REGION 8065 (N17W70) HAS BECOME
STABLE IN THE PAST 24 HOURS. THE GROUP'S MAGNETIC STRUCTURE HAS
SIMPLIFIED SIGNIFICANTLY AND IT NOW SHOWS A SIMPLE BETA
CONFIGURATION.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW. THERE IS A CHANCE FOR AN ISOLATED C-CLASS EVENT OVER THE NEXT
THREE DAYS.
IIA. Sammanfattning av geofysisk aktivitet 25-2100Z till 26-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT 24 HOURS. AN INCREASE
IS EXPECTED SOMETIME BETWEEN LATE TOMORROW AND EARLY ON DAY THREE
DUE TO EFFECTS FROM A POSSIBLE TRANSIENT ASSOCIATED WITH YESTERDAY'S
LONG DURATION X-RAY EVENT. IN ADDITION TO THIS, THERE IS A
POSSIBILITY FOR EFFECTS FROM A CORONAL HOLE BEGINNING ON THE THIRD
DAY. MOSTLY UNSETTLED LEVELS (BUT WITH POSSIBILITY FOR ACTIVE
PERIODS) ARE EXPECTED ON DAY 2 AND UNSETTLED TO ACTIVE LEVELS ARE
FORECAST FOR DAY THREE.
