Päikese aktiivsuse aruanne
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.

Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 317 Välja antud 2200Z kuni 13 NOV 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 12-2100Z kuni 13-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8763 (S14E32)
PRODUCED TWO LONG DURATION EVENTS DURING THE PERIOD. THE FIRST WAS A
M1/1F AT 13/0258Z AND THE SECOND WAS A C6/1F AT 13/1623Z. THIS
REGION HAS DECREASED IN AREA FROM YESTERDAY BUT HAS MAINTAINED A
STRONG MAGNETIC COMPLEXITY. SEVERAL OTHER REGIONS PRODUCED SUBFLARES
THROUGHOUT THE PERIOD. REGION 8760 (N14W45) REMAINS THE LARGEST
REGION ON THE SOLAR DISK WITH AN AREA OF 570 MILLIONTHS. A NEW
REGION WAS NUMBERED TODAY AS REGION 8766 (N18E68).
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
GENERALLY MODERATE. SEVERAL REGIONS HAVE M-CLASS FLARE POTENTIAL
WITH A SMALL CHANCE FOR AN X-CLASS EVENT.
IIA. Summaarne geofüüsikaline aktiivsus 12-2100Z kuni 13-2100Z
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE. MINOR STORM CONDITIONS
WERE OBSERVED AT HIGH LATITUDES AT 13/1500Z AND 13/2100Z. PROLONGED
PERIODS OF NEGATIVE BZ IN THE SOLAR WIND HAVE LED TO THESE
CONDITIONS. ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT
REMAINED AT HIGH LEVELS DURING THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE GENERALLY QUIET TO UNSETTLED. PERIODS OF ACTIVE
CONDITIONS ARE POSSIBLE THE FIRST DAY AS A CONSEQUENCE OF ONGOING
SOUTHWARD BZ IN THE SOLAR WIND.
