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 107 publicerat klockan 2200Z på 16 APR 2000IA. Analys av solfläcksgrupper och solaktivitet från 15-2100Z till 16-2100Z SOLAR ACTIVITY WAS LOW. REGION 8955 (S21E07) ENDURES AS
THE MOST COMPLEX AND ACTIVE REGION ON THE SUN. THIS REGION PRODUCED
A C6/SF AT 15/2143UT AND A C6/1N AT 16/0015UT. BOTH EVENTS WERE
ACCOMPANIED BY MINOR CENTIMETRIC BURSTS. NO SIGNIFICANT CHANGES WERE
OBSERVED IN THE OVERALL SIZE OF THIS REGION, BUT SOME DECREASE IN
COMPLEXITY WAS NOTED. REGIONS 8957 (S12W90) AND 8959 (S17W25) ALSO
PRODUCED MINOR C-CLASS X-RAY FLARES. NEW REGION 8964 (N34E21) WAS
NUMBERED TODAY.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. ISOLATED M-CLASS EVENTS ARE STILL POSSIBLE FROM REGION
8955.
IIA. Sammanfattning av geofysisk aktivitet 15-2100Z till 16-2100Z
THE GEOMAGNETIC FIELD WAS AT UNSETTLED TO MINOR STORM LEVELS. MINOR
STORMING BEGAN AFTER A WEAK SHOCK WAS OBSERVED PASSING THE ACE
SPACECRAFT AT 16/0951UT.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD SHOULD
REMAIN PREDOMINANTLY UNSETTLED TO ACTIVE WITH OCCASIONAL MINOR
STORMING AT HIGH LATITUDES. ACTIVE CONDITIONS MAY BE PROLONGED
THROUGH DAYS TWO AND THREE BY THE ARRIVAL OF A DISTURBANCE FROM THE
M4/CME EVENT ON 15/1018UT.
