A deformation of the standard light curve of meteors is studied, in which the final segment shows a sharp radiation increase (flare). Shortly before the flare a decrease of light (depression) is detected in some meteors. During the depression, evaporation intensity decreases, and on the surface of the meteor a liquid layer of overheated meteoric material is formed. The flare is due to loss and spraying of this liquid film. The mass of the molten meteoric material is shown to correspond to the mass lost during the flare.
