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 225 Välja antud 2200Z kuni 13 AUG 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 12-2100Z kuni 13-2100Z SOLAR ACTIVITY WAS LOW. REGION 8297 (N32W16) PRODUCED
AN OPTICAL SUB-FLARE AT 13/0538UT AND HAS BEEN QUIET AND STABLE
SINCE THEN. REGION 8299 (N15W01) HAS BEEN SHOWING PLAGE ENHANCEMENTS
AND FLUCTUATIONS FOR MOST OF THE DAY. THIS REGION PRODUCED 3 C-CLASS
X-RAY FLARES AND 5 OPTICAL SUB-FLARES. THE MAGNETIC CONFIGURATION
HAS BECOME MORE COMPLEX, RESULTING IN A CKO BETA-GAMMA-DELTA SPOT
GROUP. THE SIZE HAS REMAINED THE SAME AS YESTERDAY, AROUND 520
MILLIONTHS. REGION 8293 (S22W70) HAS SHOWN RENEWED ACTIVITY LATE IN
THE DAY WITH 2 C-CLASS FLARES. THE LARGEST WAS A C9/SF AT 13/1756UT.
THE MAUNA LOA SOLAR OBSERVATORY REPORTED A CORRESPONDING CME COMING
OFF OF THE WEST LIMB AT S30 AT 13/1800UT. NO OTHER SIGNIFICANT
ACTIVITY WAS NOTED AND THE REST OF THE REGIONS WERE QUIET AND STABLE
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
REGIONS 8293 AND 8297 CAN BE EXPECTED TO CONTINUE TO PRODUCE
ISOLATED C-CLASS FLARES. BOTH REGIONS ALSO HAVE A SLIGHT CHANCE OF
PRODUCING AN M-CLASS FLARE.
IIA. Summaarne geofüüsikaline aktiivsus 12-2100Z kuni 13-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET TO UNSETTLED.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO CONTINUE TO BE QUIET TO UNSETTLED.
