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 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 18-2100Z kuni 19-2100Z SOLAR ACTIVITY WAS MODERATE. REGION 8183 (N22E44)
PRODUCED AN M1/1N FLARE AT 19/0125Z. THIS REGION IS SLOWLY GROWING
AND ALSO PRODUCED THREE C-CLASS FLARES IN THE PAST 24 HOURS, THE
LARGEST OF WHICH WAS A C7/SF AT 19/1152Z. REGION 8179 (S22W56) HAS
BEGUN DECAYING SLOWLY AS IT NEARS THE WEST LIMB. THIS REGION DID NOT
PRODUCE ANY SIGNIFICANT ACTIVITY EXCEPT A FEW MINOR SUBFLARES. A
REVIEW OF THE LASCO IMAGES FROM YESTERDAY INDICATE ANOTHER PARTIAL
HALO/CME OCCURRED CONCURRENT WITH THE UNCORRELATED M1 FLARE AT
18/1112Z. A MAJORITY OF THE CME MASS APPEARED TO HAVE EJECTED FROM
THE E-SE SOLAR LIMB AND IS EXPECTED TO HAVE LITTLE GEOEFFECTIVENESS.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO REMAIN
LOW TO MODERATE FOR THE ENTIRE FORECAST PERIOD. REGIONS 8179 AND
8183 BOTH HAVE A GOOD CHANCE OF CONTINUED C-CLASS FLARING AND A
POTENTIAL FOR ISOLATED M-CLASS ACTIVITY. BOTH REGIONS ALSO HAVE A
SMALL CHANCE OF ISOLATED X-CLASS ACTIVITY.
IIA. Summaarne geofüüsikaline aktiivsus 18-2100Z kuni 19-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET. THE GREATER THAN 2 MEV
ENERGETIC ELCTRON FLUX REMAINED IN THE HIGH RANGES.
IIB. Geofüüsikalise aktiivsuse ennustus
GEOMAGNETIC ACTIVITY IS
EXPECTED TO BE QUIET TO UNSETTLED FOR THE NEXT 24 HOURS THEN
GENERALLY QUIET FOR THE REMAINDER OF THE FORECAST PERIOD IN MID
LATITUDES. HIGH LATITUDES MAY EXPERIENCE MOSTLY UNSETTLED ACTIVITY
OVER THE ENTIRE FORECAST PERIOD.
