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 196 Välja antud 2200Z kuni 15 JUL 1998IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 14-2100Z kuni 15-2100Z SOLAR ACTIVITY WAS LOW. THE LARGEST EVENT OF THE PERIOD
WAS A C6/SF WITH MINOR CENTIMETRIC RADIO BURSTS FROM REGION 8270
(S21W00). REGION 8270 ALSO PRODUCED SEVERAL SMALL C-CLASS FLARES.
SLIGHT DECAY OCCURRED IN THIS REGION BUT SMALL AREAS OF MAGNETIC
COMPLEXITY REMAINED. NEW REGION 8272 (S28E56) PRODUCED A C5/SF AT
15/1046Z. THIS REGION IS A SMALL CLASS B SUNSPOT GROUP. NEW REGION
8273 (S27E22) EMERGED AT A MODERATE PACE NEAR THE BASE OF AN
EXISTING FILAMENT.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD REMAIN
PREDOMINANTLY LOW WITH REGIONS 8270 AND 8273 PRODUCING OCCASIONAL
C-CLASS FLARES. REGION 8270 RETAINS THE CAPABILITY OF PRODUCING AN
ISOLATED M-CLASS EVENT BUT THAT POSSIBILITY IS DECREASING AS THE
REGION DECAYS. PAST STATISTICAL STUDIES INDICATE THE PRE-EXISTING
FILAMENT NEAR EMERGING REGION 8273 COULD ERUPT IN THE NEAR FUTURE.
IF ERUPTION OCCURS, IT IS NOT LIKELY THAT A LARGE SPOTLESS FLARE
WOULD OCCUR SINCE THE MAGNETIC FIELD STRENGTHS AROUND THE FILAMENT
ARE LOW.
IIA. Summaarne geofüüsikaline aktiivsus 14-2100Z kuni 15-2100Z
THE GEOMAGNETIC FIELD WAS QUIET.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD SHOULD
BECOME QUIET TO UNSETTLED FOR 16-17 JUL. ISOLATED PERIODS OF ACTIVE
CONDITIONS ARE POSSIBLE DURING THAT PERIOD AS A RESULT OF THE M4/1B
FLARE ON 14 JUL. PREDOMINANTLY QUIET LEVELS ARE EXPECTED TO RETURN
ON 18 JUL.
