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 070 Välja antud 2200Z kuni 11 MAR 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 10-2100Z kuni 11-2100Z SOLAR ACTIVITY WAS LOW. REGION 8483 (S18W61) SHOWED
GROWTH AND FREQUENT SMALL FLARE ACTIVITY, INCLUDING A C8/SF AT
0009Z. NEW REGION 8487 (N17E63) WAS ALSO ACTIVE TODAY AND PRODUCED A
C6/SF AT 2034Z. REGION 8485 (N22E27) GREW SLOWLY AND IS CURRENTLY
THE LARGEST SUNSPOT GROUP ON THE DISK, BUT COULD ONLY MUSTER A
COUPLE SUBFLARES.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THERE IS A SLIGHT CHANCE FOR AN ISOLATED M-CLASS EVENT, HOWEVER,
FROM ANY OF REGIONS 8485, 8484 OR 8483.
IIA. Summaarne geofüüsikaline aktiivsus 10-2100Z kuni 11-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO ACTIVE. AN INITIALLY QUIET FIELD
BECAME MOSTLY UNSETTLED AFTER 11/0000Z AND CONTINUED UNSETTLED
THROUGH THE END OF THE DAY, WITH THE EXCEPTION OF AN ISOLATED ACTIVE
PERIOD AT HIGH LATITUDES BETWEEN 1200-1500Z.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO BE MOSTLY UNSETTLED FOR THE NEXT 36 TO 48 HOURS. THERE
IS A FAIR CHANCE FOR AN INCREASE TO ACTIVE LEVELS BEGINNING LATE ON
THE 13TH OR PERHAPS ON THE 14TH AS A RESPONSE TO YESTERDAY'S
FILAMENT ERUPTION. NOTE ALSO THAT THERE IS ALSO AN ENHANCED,
PROBABILITY FOR STORM LEVEL CONDITIONS DURING THIS TIME FRAME.
