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 312 Välja antud 2200Z kuni 08 NOV 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 07-2100Z kuni 08-2100Z SOLAR ACTIVITY REMAINED AT A LOW LEVEL. THE LARGEST
EVENT OF THE PERIOD WAS A MODERATE DURATION C8/SF FROM REGION 8759
(N13E59) AT 08/1852Z. THIS REGION HAS WHITE LIGHT AREA OF OVER 800
MILLIONTHS AND MIXED MAGNETIC FIELDS. THERE MAY BE A WEAK DELTA
CONFIGURATION IN THE TRAILER OF THIS REGION. DEPARTING REGION 8749
(S18W88) PRODUCED A C5/SF AT 08/0602Z. REGION 8760 EMERGED STEADILY
DURING THE PERIOD AND PRODUCED A C4/SN AT 08/1117Z.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD BECOME MODERATE
DURING THE PERIOD. THE LARGE AREA AND MAGNETIC COMPLEXITY OF REGION
8759 INDICATE THAT M-CLASS EVENTS ARE PROBABLE FROM THIS AREA. THE
FREQUENCY OF M-CLASS FLARES SHOULD BE EVERY 1-2 DAYS SINCE THE
REGION DOES NOT APPEAR TO BE GROWING. REGION 8760 SHOULD BEGIN TO
PRODUCE MORE C-CLASS EVENTS AS IT MATURES. THERE IS A SMALL
POSSIBILITY OF AN X-CLASS EVENT FROM REGION 8759 DURING THE NEXT
THREE DAYS.
IIA. Summaarne geofüüsikaline aktiivsus 07-2100Z kuni 08-2100Z
THE GEOMAGNETIC FIELD RANGED FROM UNSETTLED TO MAJOR STORM LEVELS.
THE MOST DISTURBED PERIOD WAS FROM 08/0600-1500Z. A FEW HIGH
LATITUDE SITES EXPERIENCED BRIEF SEVERE STORM LEVELS DURING THAT
PERIOD. SOLAR WIND DATA INDICATE THIS DISTURBANCE IS CORONAL HOLE
RELATED.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD
REMAIN DISTURBED THROUGHOUT THE NEXT THREE DAYS. MID LATITUDES CAN
EXPECT OCCASIONAL PERIODS OF MINOR STORMING AND HIGH LATITUDES
SHOULD EXPERIENCE ISOLATED PERIODS OF MAJOR STORMING. THE CORONAL
HOLE CAUSING THIS DISTURBANCE IS QUITE WIDE AND THE HIGH SPEED
STREAM FROM IT SHOULD IMPACT THE EARTH FOR APPROXIMATELY THE NEXT
FIVE DAYS.
