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 195 Välja antud 2200Z kuni 14 JUL 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 13-2100Z kuni 14-2100Z SOLAR ACTIVITY BECAME MODERATE. REGION 8270 (S17E15)
PRODUCED AN M4/1B FLARE AT 14/1259Z. A 250 F.U. BURST AT 2695 MHZ
AND STRONG TYPE IV ACCOMPANIED THIS IMPULSIVE EVENT. A TYPE II BURST
MAY WELL HAVE OCCURRED WITH THIS EVENT BUT WAS PREDOMINANTLY
OBSCURED BY THE TYPE IV. OPTICALLY UNCORRELATED C2 FLARES OCCURRED
AT 14/0225Z AND 14/1903Z. AT 14/1100Z REGION 8269 (N18E17) PRODUCED
A C1/SF FLARE. REGION 8270 IS SMALL AND RELATIVELY STABLE IN AREA
BUT POSSESSES TIGHT MAGNETIC GRADIENTS AND HIGH RESOLUTION
MAGNETOGRAPHS INDICATE A DELTA CONFIGURATION IN THE CENTER OF THE
REGION.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE
PREDOMINANTLY LOW FOR THE NEXT THREE DAYS. ISOLATED M-CLASS EVENTS
FROM REGION 8270 ARE POSSIBLE. HOWEVER, ONLY SLIGHT MAGNETIC
SIMPLIFICATION IN THIS DIMINUTIVE REGION WOULD RESULT IN A LARGE
DECREASE OF THAT POSSIBILITY.
IIA. Summaarne geofüüsikaline aktiivsus 13-2100Z kuni 14-2100Z
THE GEOMAGNETIC FIELD WAS QUIET AT ALL LATITUDES.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD
REMAIN QUIET FOR 15 JUL. PREDOMINANTLY QUIET TO UNSETTLED CONDITIONS
ARE EXPECTED ON 15-16 JUL WITH PERIODS OF ACTIVE LEVELS POSSIBLE
DURING THAT PERIOD DUE TO THE M4/1B FLARE MENTIONED ABOVE. THE LACK
OF MASS EJECTION INFORMATION FROM THE NOW CRIPPLED SOHO SATELLITE
LIMITS CONFIDENCE IN THIS FORECAST.
