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 244 Välja antud 2200Z kuni 31 AUG 2000IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 30-2100Z kuni 31-2100Z SOLAR ACTIVITY WAS LOW. REGION 9143 (S18W20) PRODUCED
TODAY'S LARGEST EVENT, A C1/SF AT 0656Z. THIS GROUP HAS SHOWN SLIGHT
DECAY DURING THE PAST 24 HOURS. REGION 9149 (N12E32) CONTINUES TO BE
THE LARGEST GROUP ON THE DISK BUT WAS STABLE AND QUIET. NEW REGIONS
9150 (N11E51), 9151 (N05E42), AND 9152 (N17E75) ARE SMALL, STABLE
GROUPS THAT WERE ASSIGNED DURING THE PAST 24 HOURS.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINANTLY LOW. THERE IS A SLIGHT-TO-FAIR CHANCE FOR AN ISOLATED
M-CLASS EVENT DURING THE NEXT THREE DAYS.
IIA. GEOPHYSICAL ACTIVITY SUMMARY 30/2100Z TO 31/2100Z:
THE GEOMAGNETIC FIELD WAS UNSETTLED TO ACTIVE. SOLAR WIND
OBSERVATIONS INDICATE THE CONTINUED INFLUENCE OF A HIGH-SPEED
CORONAL HOLE STREAM. THE GREATER THAN 2 MEV ELECTRON FLUX AT GEOSYNCHRONOUS
ORBIT EXCEEDED HIGH LEVELS DURING THE PAST 24 HOURS.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE UNSETTLED WITH A CHANCE FOR ISOLATED ACTIVE PERIODS
DURING THE NEXT 24 HOURS AS EFFECTS FROM THE CORONAL HOLE STREAM ARE
EXPECTED TO CONTINUE. PREDOMINANTLY UNSETTLED LEVELS ARE EXPECTED FOR
THE SECOND AND THIRD DAYS.
