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 078 Välja antud 2200Z kuni 19 MAR 1999IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 18-2100Z kuni 19-2100Z SOLAR ACTIVITY BECAME VERY LOW. REGION 8485 (N22W78)
HAS QUIETED DOWN CONSIDERABLY AS IT NEARS THE WEST LIMB. LIMB
PROXIMITY INHIBITS A THOROUGH ANALYSIS, BUT IT APPEARS NOW AS A
SIMPLE BETA GROUP IN DECAY. A PROMINENCE ERUPTED FROM THE SE LIMB
AROUND 19/1620Z. SPACE-BASED IMAGERY INDICATE A CORONAL MASS
EJECTION OCCURRED WITH THE ERUPTION, BUT MATERIAL DOES NOT APPEAR
EARTHBOUND. FIVE NEW REGIONS WERE NUMBERED TODAY - REGIONS 8492
(S27W46), 8493 (N19W22), 8494 (S22E15), 8495 (S21E61), AND 8496
(S11W03). REGION 8493 APPEARS TO HAVE THE HIGHEST ACTIVITY POTENTIAL
OF THESE NEW REGIONS AS IT QUICKLY DEVELOPED INTO A C CLASS GROUP
WITH OVER 20 SPOTS VISIBLE IN WHITE LIGHT. NO SIGNIFICANT ACTIVITY
WAS NOTED IN THE REMAINING REGIONS.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW.
THERE IS STILL A SMALL CHANCE FOR AN M-CLASS FROM REGION 8485 AS IT
ROTATES AROUND THE WEST LIMB, BUT THE LIKELIHOOD IS DIMINISHING AS
THE REGION CONTINUES TO DECAY.
IIA. Summaarne geofüüsikaline aktiivsus 18-2100Z kuni 19-2100Z
THE GEOMAGNETIC FIELD WAS MOSTLY QUIET WITH ISOLATED UNSETTLED
PERIODS AT HIGH LATITUDES.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO REMAIN QUIET TO UNSETTLED.
