Abstract: Processing of pyrotechnic composition flare image by developed software allows you to select the shape and dimensions of the shining body of the flare, divide it into zones according to the brightness level, determine the temperature and radiation force of each isolated zone. The temperature of the flare zone was determined by comparing the brightness of the flare zones with the brightness of a known object. In the work shown, the maximum of the temperature in the flare reaches 2523 K, and the radiation force in the visible spectrum is 442 W/sr.

Keywords: pyrotechnic composition, flare, zone, brightness, temperature, radiation force, luminous body.
