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 143 Välja antud 2200Z kuni 23 MAY 1997IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 22-2100Z kuni 23-2100Z SOLAR ACTIVITY REMAINED VERY LOW. REGION 8040 (N07W40)
DECAYED AND PRODUCED ONLY MINOR FLUCTUATIONS. A SMALL REGION ROTATED
AROUND THE LIMB AND WAS NUMBERED AS NEW REGION 8046 (S26E68). THE
LARGE PROMINENCES ON THE SOUTHEAST LIMB ON 22 MAY FADED SOMETIME
BEFORE 23/1500Z.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY SHOULD CONTINUE AT VERY
LOW LEVELS FOR THE NEXT THREE DAYS. THERE IS A SLIGHT POSSIBILITY OF
A C-CLASS FLARE FROM DECAYING REGION 8040.
IIA. Summaarne geofüüsikaline aktiivsus 22-2100Z kuni 23-2100Z
THE GEOMAGNETIC FIELD WAS QUIET. THE DISTURBANCE RELATED TO THE CME
ON 21 MAY HAS NOT MATERIALIZED AT THE TIME INITIALLY EXPECTED.
ENERGETIC ELECTRON FLUXES AT GEOSYNCHRONOUS ORBIT WERE BELOW EVENT
THRESHOLD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
FORECAST TO BE AT ACTIVE TO MINOR STORM LEVELS ON 24 MAY AND EARLY
25 MAY. ISOLATED MAJOR STORMING IS POSSIBLE DURING THIS DISTURBANCE.
THE CONFIDENCE THAT THE CME WILL IMPACT THE EARTH IS HIGH DUE TO THE
NATURE OF SPACE OBSERVATIONS OF THE EVENT. HOWEVER, THE TIMING OF
IMPACT IS DIFFICULT TO PREDICT. QUIET TO UNSETTLED CONDITIONS ARE
EXPECTED ON 26 MAY AFTER THE DISTURBANCE PASSES.
