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 310 Välja antud 2200Z kuni 06 NOV 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 05-2100Z kuni 06-2100Z SOLAR ACTIVITY DECREASED TO LOW LEVELS. THREE SMALL
C-CLASS X-RAY FLARES WERE DETECTED, NONE OF WHICH WERE OPTICALLY
CORRELATED. REGION 8749 (S18W64) CONTINUED TO SLOWLY DECAY AND
PRODUCED A SINGLE SUBFLARE EARLY IN THE PERIOD. REGION 8747 (N10W64)
ALSO SHOWED SIGNS OF SLOW DECAY. REGION 8757 (N38W03) SHOWED A MINOR
INCREASE IN SPOT COUNT AND AREA, BUT PRODUCED NO FLARES. REGION 8755
(N21E57) WAS DIVIDED INTO TWO REGIONS WITH THE TRAILING REGION
NUMBERED AS NEW REGION 8758 (N18E64). NEW REGION 8759 (N10E78) WAS
ALSO NUMBERED. IT APPEARED TO BE THE RETURN OF OLD ACTIVE REGION
8731.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGIONS 8749 AND 8759 MAY PRODUCE ISOLATED M-CLASS
FLARES.
IIA. Summaarne geofüüsikaline aktiivsus 05-2100Z kuni 06-2100Z
THE GEOMAGNETIC FIELD WAS AT MOSTLY QUIET LEVELS.
IIB. Geofüüsikalise aktiivsuse ennustus
QUIET TO UNSETTLED LEVELS ARE
EXPECTED DURING THE FIRST DAY. CORONAL HOLE EFFECTS ARE EXPECTED TO
COMMENCE EARLY ON 08 NOVEMBER, THEN CONTINUE THROUGH THE REST OF THE
PERIOD. ACTIVE TO MINOR STORM LEVELS ARE EXPECTED DURING THE
DISTURBANCE. THE GREATER THAN 2 MEV ELECTRON FLUX IS EXPECTED TO
REACH HIGH LEVELS LATE IN THE PERIOD.
