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 011 publicerat klockan 2200Z på 11 JAN 2000IA. Analys av solfläcksgrupper och solaktivitet från 10-2100Z till 11-2100Z SOLAR ACTIVITY WAS MODERATE DUE TO A SINGLE
UNCORRELATED M1 X-RAY EVENT AT 11/0424UT. REGION 8824 (S13E47) WAS
THE MOST ACTIVE REGION PRODUCING SEVERAL C-CLASS EVENTS IN
CONJUNCTION WITH OPTICAL SUBFLARES, THE LARGEST BEING A C9/SF AT
11/0116UT. REGION 8824 DEVELOPED INTO A MORE COMPLEX BETA-GAMMA
MAGNETIC STRUCTURE DURING THE PERIOD. A TEN DEGREE LONG DISAPPEARING
SOLAR FILAMENT (S34E41) WAS NOTED AT 11/1440UT. TWO NEW REGIONS WERE
NUMBERED DURING THE PERIOD: 8826 (N18W21) AND 8827 (S11W20).
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE.
IIA. Sammanfattning av geofysisk aktivitet 10-2100Z till 11-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET TO UNSETTLED WITH TWO ACTIVE
PERIODS OCCURRING AT THE END OF THE REPORTING DAY. THIS INCREASE IN
ACTIVITY IS DUE TO HIGH-SPEED SOLAR WIND STREAM. THE ENERGETIC
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT REACHED MODERATE LEVELS TODAY.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PRIMARILY UNSETTLED FOR THE NEXT 24 HOURS. THE
EFFECTS OF A HIGH-SPEED SOLAR WIND STREAM MAY RESULT IN OCCASIONAL
ACTIVE CONDITIONS. THIS DISTURBANCE SHOULD FADE QUICKLY, GIVING WAY
TO QUIET CONDITIONS BY THE END OF THE PERIOD.
