description In this paper, we discuss about the prediction of solar flare through sunspot digital optical observation, based on 4 sets of H alpha archive data from the Big Bear Solar Observatory. The brightness and pattern of 3D surface plot of the sunspot areas are analyzed for a few hours before and after the eruption of solar flare. Results show that the sunspot areas are gradually merged and at its peak brightness before the eruption of solar flare. The possible cause of these two precursors of solar flare will then be discussed.
