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.
Päikese ja geofüüsikalise aktiivsuse aruanne 1999 Oct 02 2200 UTCValminud NOAA © SWPC ja töödeldud SpaceWeatherLive.com-iga
Ühine USAF / NOAA päikese- ja geofüüsikaalase aktiivsuse aruanne
SDF number 275 Välja antud 2200Z kuni 02 OCT 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 01-2100Z kuni 02-2100Z SOLAR ACTIVITY WAS LOW. NUMEROUS MINOR C-CLASS X-RAY
EVENTS OCCURRED WITH NO OPTICAL CORRELATION EXCEPT WITH A C3/SF
OBSERVED AT 02/1828Z FROM REGION 8716 (N21E70). THE LARGEST EVENT
WAS A C6 AT 02/0156Z. SURGING WAS OBSERVED FROM THE NORTHEAST AND
SOUTHEAST LIMB AS TWO ACTIVE REGIONS ARE STARTING TO ROTATE ONTO THE
DISK. NEW REGION 8716 (N21E70) WAS NUMBERED.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
WITH A SLIGHT CHANCE OF AN M-CLASS X-RAY EVENT MOST LIKELY OCCURRING
FROM ONE OF THE MORE ACTIVE REGIONS NEAR THE EAST LIMB.
IIA. Summaarne geofüüsikaline aktiivsus 01-2100Z kuni 02-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. THE GREATER THAN 2 MEV
ELECTRON FLUX AT GEOSYNCHRONOUS ORBIT ALTERNATED BETWEEN MODERATE TO
HIGH LEVELS THROUGHOUT THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE QUIET TO ACTIVE DURING THE FIRST DAY OF THE PERIOD
THEN BECOMING MORE QUIET TO UNSETTLED. ISOLATED ACTIVE CONDITIONS
ARE MORE LIKELY TO OCCUR IN THE HIGHER LATITUDES DURING THE FIRST
DAY OF THE PERIOD.
