Solar flares are huge explosions in the sun that emit of high energy particles and X-rays. The explosions occur near sunspots, because sunspots store much energy in their strong magnetic fields and emit this energy instantly. Ejections from solar flares sometimes effect significant impacts the earth. Solar flares are the cause of radio and GPS failures and major power outages. To protect our lives, it is necessary to observe the sun and predict solar flares. The research focuses on a system for quantifying sunspot images using image processing. The method is proposed to characterize the sunspot growth process more clearly and mathematically using solar images. These images of visible light show the outlines of a sunspot by image processing. Because the sun is a sphere, the latitude and longitude parameters affect the outlines. The system corrects the parameters and draws the outlines. These outlines form sunspot area and help to survey the character of sunspot growth that occurred large solar flares.
