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 343 Välja antud 2200Z kuni 09 DEC 1997IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 08-2100Z kuni 09-2100Z SOLAR ACTIVITY WAS VERY LOW. REGIONS 8116 (N25W15), A 5
SPOT CSO GROUP, AND 8119 (N32W13), AN 8 SPOT CRO GROUP, ARE IN CLOSE
PROXIMITY AND EXHIBITED SLOW GROWTH IN THE PAST 24 HOURS. REGIONS
8118 (S39E25), A 7 SPOT CAO, AND 8120 (S22E22), A 9 SPOT CRO, ALSO
SHOWED SIGNS OF DEVELOPMENT BUT ALL 4 REGIONS MAINTAIN SIMPLE
MAGNETIC CONFIGURATIONS AND HAVE YET TO PRODUCE ANY FLARE ACTIVITY.
A NEW SMALL COMPACT PLAGE REGION IS DEVELOPING NEAR N26W38 BUT NO
SPOTS ARE VISIBLE IN WHITE LIGHT YET. REMAINING REGIONS HAVE BEEN
QUIET AND STABLE.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE VERY
LOW TO LOW. ALL 4 SPOT REGIONS MENTIONED ABOVE EXHIBITED PERIODIC
POINT BRIGHTNINGS IN THE PAST 24 HOURS. SEVERAL MINOR RADIO BURSTS
AND SWEEPS ALSO OCCURRED INDICATING GROWTH. VERY ISOLATED C-CLASS
FLARING IS POSSIBLE FROM THESE REGIONS IF GROWTH CONTINUES.
IIA. Summaarne geofüüsikaline aktiivsus 08-2100Z kuni 09-2100Z
THE GEOMAGNETIC FIELD HAS BEEN QUIET AT ALL LATITUDES. SOLAR WIND
VELOCITY HAS DROPPED TO NEAR 200 KM/S.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
EXPECTED TO REACH UNSETTLED TO ACTIVE CONDITIONS BY TOMORROW DUE TO
THE VERY LONG DURATION C1 FLARE AND ASSOCIATED HALO/CME ON 6
DECEMBER. DISTURBED CONDITIONS SHOULD PERSIST THROUGH 11 DECEMBER
AND RETURN TO QUIET BY THE 12TH.
