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 100 publicerat klockan 2200Z på 10 APR 1997IA. Analys av solfläcksgrupper och solaktivitet från 09-2100Z till 10-2100Z SOLAR ACTIVITY WAS VERY LOW. ONLY MINOR X-RAY ACTIVITY
WAS NOTED OVER THE PAST 24 HOURS. A SUB FAINT OPTICAL FLARE WAS
OBSERVED IN REGION 8029 (N24W34). THIS NEW-CYCLE REGION HAS SHOWN
GOOD GROWTH OVER THE PAST 24 HOURS AND IS NOW A DAO SPOT GROUP. NEW
REGION 8030 (N11W31), AN AXX SPOT GROUP, WAS NUMBERED TODAY. REGION
8027 (S28W27) CONTINUES TO DECAY AND IS NOW A MERE AXX SPOT GROUP.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8029 HAS A FAIR CHANCE OF C-CLASS ACTIVITY AND AN
OUTSIDE CHANCE OF AN ISOLATED M-CLASS FLARE.
IIA. Sammanfattning av geofysisk aktivitet 09-2100Z till 10-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED AT ALL LATITUDES. A
MINOR INCREASE IN ACTIVITY AT SATELLITE ALTITUDE AND HIGH LATITUDES
BEGAN ABOUT 10/1300Z. SPACE-BASED SENSORS INDICATE INCREASED SOLAR
WIND DENSITY AND VELOCITY BEGAN AT ABOUT 10/1300Z, PROBABLY IN
CONJUNCTION WITH THE FORECAST ARRIVAL OF MONDAY'S CME PLASMA CLOUD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED TO ACTIVE FOR THE NEXT 48 TO 60 HOURS AS A
RESULT OF MONDAY'S CME IN CONJUNCTION WITH A WEAK, BUT FAVORABLY
POSITIONED CORONAL HOLE. THIRD DAY ACTIVITY IS EXPECTED TO GRADUALLY
DIMINISH TO MOSTLY UNSETTLED LEVELS.
