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 086 publicerat klockan 2200Z på 27 MAR 1997IA. Analys av solfläcksgrupper och solaktivitet från 26-2100Z till 27-2100Z SOLAR ACTIVITY WAS LOW. A C1 X-RAY EVENT OCCURRED AT
1035Z. ALTHOUGH THERE WERE NO TIME-COINCIDENT OBSERVATIONS AVAILABLE
TO PINPOINT THE SOURCE, A LIKELY CANDIDATE IS NEW REGION 8026
(S26E73). THIS REGION ROTATED INTO VIEW TODAY AS A SMALL BUT ACTIVE
BXO BETA SUNSPOT GROUP, AND WAS OBSERVED TO PRODUCE OCCASIONAL
SUBFLARE ACTIVITY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. THERE IS A POSSIBILITY FOR AN ADDITIONAL C-CLASS
EVENT FROM REGION 8026 OVER THE NEXT THREE DAYS.
IIA. Sammanfattning av geofysisk aktivitet 26-2100Z till 27-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE FROM 26/2100 THROUGH
27/0100Z, BUT BECAME REMARKABLY QUIET AFTER 27/0100Z. QUIET
CONDITIONS PREVAILED FROM 27/0100-27/2100Z WITH THE EXCEPTION OF
SOME VERY BRIEF UNSETTLED TO ACTIVE LEVEL CONDITIONS AT A FEW HIGH
LATITUDE SITES BETWEEN 0700-1200Z. THE GREATER THAN 2 MEV ELECTRON
FLUXES ATTAINED HIGH LEVELS (GREATER THAN 1000 PFU) DURING THE
REPORTING PERIOD.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED FOR THE NEXT THREE DAYS.
