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 015 publicerat klockan 2200Z på 15 JAN 1999IA. Analys av solfläcksgrupper och solaktivitet från 14-2100Z till 15-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8440 (N20E42)
CONTINUED AS THE DOMINANT ACTIVE REGION ON THE DISK AS IT PRODUCED
ANOTHER M-CLASS EVENT (M1/1F AT 0721Z), AS WELL AS NUMEROUS C-CLASS
FLARES. THE LARGEST C-CLASS EVENT WAS A C9/1B AT 1444Z. THE REGION
CONSISTS OF NEARLY 30 SPOTS, BRIGHT PLAGE, AND A POSSIBLE MIXED
POLARITY (DELTA) CONFIGURATION IN THE SOUTHERN PORTION OF THE
INTERMEDIATE SPOTS. REGION 8439 (S24E41) GENERATED A C3/1F AT 1314Z,
BUT LITTLE ELSE. IT HAS A SLIGHT DEGREE OF MAGNETIC COMPLEXITY AS
WELL AS APPROXIMATELY 25 SPOTS. ELSEWHERE, THE REMAINDER OF THE DISK
AND LIMBS WERE QUIET.
IB. Prognos för solaktivitet
SOLAR ACTIVITY IS EXPECTED TO REMAIN
MODERATE. CONTINUED M-CLASS FLARES ARE LIKELY FROM REGION 8440, AND
SHOULD FURTHER DEVELOPMENT OCCUR, REGION 8439.
IIA. Sammanfattning av geofysisk aktivitet 14-2100Z till 15-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE AT MIDDLE LATITUDES, AND
UNSETTLED TO MINOR STORM AT HIGH LATITUDES. A HIGH-SPEED SOLAR WIND
STREAM HAS PROLONGED THE CME-RELATED DISTURBANCE THAT BEGAN ON 13
JANUARY. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS
ORBIT REACHED HIGH LEVELS AT APPROXIMATELY 1500Z.
IIB. Prognos för geofysisk aktivitet
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE PRIMARILY QUIET TO UNSETTLED THROUGHOUT THE PERIOD.
SUBSTORMS MAY BRING BRIEF ACTIVE LEVELS DURING LOCAL NIGHTTIMES OVER
THE NEXT 24 HOURS.
