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 112 publicerat klockan 2200Z på 22 APR 1997IA. Analys av solfläcksgrupper och solaktivitet från 21-2100Z till 22-2100Z SOLAR ACTIVITY WAS VERY LOW. NO FLARES OCCURRED. NEW
REGION 8035 (N17E64), A SINGLE SPOT 'AXX' ALPHA GROUP WAS NUMBERED
TODAY. AN 18 DEGREE DISAPPEARING FILAMENT WAS REPORTED OVERNIGHT
FROM APPROXIMATE LOCATION N47E27.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
VERY LOW.
IIA. Sammanfattning av geofysisk aktivitet 21-2100Z till 22-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO ACTIVE AT MIDDLE LATITUDES
AND QUIET TO MINOR STORM AT HIGH LATITUDES FOR THE PAST 24 HOURS.
TODAY'S ACTIVE AND MINOR STORM CONDITIONS WERE CONFINED TO THE
INTERVAL 22/0000-0600Z, MARKING THE END OF A DISTURBANCE THAT BEGAN
YESTERDAY AT APPROXIMATELY 21/1200Z. WIND DATA SUGGEST THAT THIS
DISTURBANCE WAS DUE TO A TRANSIENT IN THE SOLAR WIND. ACTIVITY
FOLLOWING THE END OF THE DISTURBANCE DECREASED TO MOSTLY QUIET FOR
THE REMAINDER OF THE REPORTING PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT THREE DAYS, WITH THE
CHANCE FOR ISOLATED PERIODS OF ACTIVE CONDITIONS.
