In recent years, studies have shown that the explosions occurring on the Sun have a significant impact on the terrestrial environment, even though the Sun is far away from the Earth. This finding has posed questions about how the impact of such explosions can spread through the interplanetary space within the solar system, and what the consequences of these phenomena are. This work briefly describes the basics of the solar activity observations made in Hα light and at shifted wavelenghts, in order to get information related to the movement of hydrogen atoms (gas) at a high velocity in the chromosphere toward the observer using the Doppler effect, it is possible to determine the velocity of the filaments or similar structures from the solar image obtained with the Flare Monitoring Telescope (FMT). We present also ilustrative examples relating to the Sun's impact on the terrestirial environment.
