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 098 publicerat klockan 2200Z på 08 APR 1997IA. Analys av solfläcksgrupper och solaktivitet från 07-2100Z till 08-2100Z SOLAR ACTIVITY WAS VERY LOW. REGION 8027 (S28E00)
REMAINED QUIET AND STABLE. THE SLOW DECAY OF THIS REGION HAS
APPARENTLY STABILIZED. NEW REGION 8028 (S07W50), AN AXX SPOT GROUP,
WAS NUMBERED TODAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. REGION 8027 STILL HAS A CHANCE FOR C-CLASS ACTIVITY AND
A DIMINSHED CHANCE OF ISOLATED M-CLASS ACTIVITY. REGION 8028 IS NOT
EXPECTED TO BE SIGNIFICANTLY ACTIVE AT THIS TIME.
IIA. Sammanfattning av geofysisk aktivitet 07-2100Z till 08-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT 24 TO 36 HOURS. THE
FIELD IS EXPECTED TO EXPERIENCE INCREASING ACTIVITY BY THE END OF
DAY TWO AND BE UNSETTLED TO ACTIVE BY DAY THREE. HIGH LATITUDE
STATIONS MAY EXPERIENCE ACTIVE TO MINOR STORMING DURING THIS PERIOD.
ACTIVITY WILL BE A RESULT OF THE APPARENT CME ASSOCIATED WITH
YESTERDAY'S C6/3N FLARE. AN INDEPENDENT SOURCE OF SOLAR DATA
INDICATES THAT A SIGNIFICANT CORONAL MASS EJECTION WAS OBSERVED IN
CONJUNCTION WITH THE FLARE. THIS DATA CORROLATES WELL WITH REPORTED
TYPE II AND IV SWEEPS ASSOCIATED WITH THE FLARE.
