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 016 Välja antud 2200Z kuni 16 JAN 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 15-2100Z kuni 16-2100Z SOLAR ACTIVITY WAS MODERATE. TWO M-CLASS FLARES WERE
REPORTED: AN M3 AT 16/1207UT AND AN M1 AT 16/1956UT. ALTHOUGH BOTH
FLARES WERE OPTICALLY UNCORRELATED THEY WERE MOST LIKELY PRODUCED BY
REGION 8440 (N19E29). REGION 8440 IS THE DOMINANT ACTIVE REGION ON
THE DISK. BESIDES THE PROBABLE M-CLASS FLARES IT HAS PRODUCED
NUMEROUS C-CLASS FLARES DURING THE DAY. THE REGION IS CURRENTLY A 31
SPOT EAI GROUP WITH A BETA GAMMA MAGNETIC CLASSIFICATION. THE OTHER
ACTIVE REGION WAS 8339 (S24E28). 8339 PRODUCED A C1/SF AT 16/0137UT
BUT HAS SHOWN NO ACTIVITY SINCE THEN. REST OF THE DISK AND LIMBS
WERE QUIET.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO REMAIN
MODERATE. CONTINUED M-CLASS FLARES ARE LIKELY FROM REGION 8440 AND
POSSIBLY ISOLATED M-CLASS FLARES FROM 8439.
IIA. Summaarne geofüüsikaline aktiivsus 15-2100Z kuni 16-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT WAS AT HIGH LEVELS ALL DAY
WITH THE EXCEPTION OF THE PERIOD 16/0000UT TO 16/0600UT. DURING THAT
PERIOD THE FLUX FELL BELOW THRESHOLD LEVELS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FILED IS
EXPECTED TO BE QUIET TO UNSETTLED.
