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 328 Välja antud 2200Z kuni 24 NOV 1997IA. Päikese aktiivsete piirkondade ja päikeseaktiivsuse analüüs alates 23-2100Z kuni 24-2100Z SOLAR ACTIVITY BECAME MODERATE. AN OPTICALLY
UNCORRELATED M1 FLARE OCCURRED AT 24/1950Z. SOON ANALYSTS WERE
OBSERVING THE SUN DURING THE EVENT AND THEY DID NOT OBSERVE ANY
ENHANCEMENT IN CURRENT DISK REGIONS. OLD REGION 8103 IS DUE TO
RETURN AT THE NORTHEAST LIMB IN ABOUT A DAY AND A HALF AND THIS
COULD BE THE SOURCE OF THE M1. REGION 8103 WAS GROWING AT WEST LIMB
TRANSIT AND RECENT SPACE-BASED IMAGES SHOW ENHANCED EMISSION OVER
THE NORTHEAST LIMB. REGION 8108 (N20W65) PRODUCED A C3/1F AT
24/0400Z. THIS REGION DISPLAYED DECAY AND CONTINUED REDUCTION OF
MAGNETIC COMPLEXITY. OTHER DISK REGIONS SHOWED LITTLE EVOLUTION.
IB. Päikese aktiivsuse ennustus
SOLAR ACTIVITY IS EXPECTED TO BE LOW
TO MODERATE. REGION 8108 SHOULD PRODUCE OCCASIONAL C-CLASS EVENTS
BUT AT A DECREASING FREQUENCY. IT IS DIFFICULT TO ASSESS THE FLARE
POTENCY OF A REGION BEHIND THE LIMB. A PERSISTENCE FORECAST ARGUES
FOR OCCASIONAL M-CLASS EVENTS.
IIA. Summaarne geofüüsikaline aktiivsus 23-2100Z kuni 24-2100Z
THE GEOMAGNETIC FIELD WAS QUIET TO UNSETTLED. NEAR 24/1200Z, SOLAR
WIND VELOCITY DROPPED TO NEAR 450 KM/S. ENERGETIC ELECTRON FLUXES AT
GEOSYNCHRONOUS ORBIT BECAME HIGH DURING THE PERIOD.
IIB. Geofüüsikalise aktiivsuse ennustus
THE GEOMAGNETIC FIELD IS
FORECAST TO BE PREDOMINANTLY QUIET FOR THE NEXT THREE DAYS.
