Abstract
Several results of the solar irradiance observations carried out with the IPHIR experiment on board the Soviet spacecraft within the PHOBOS Project are considered. The time variations of the power spectrum of 5-min solar oscillations is discussed. It is found that the lines are generated inhomogeneously in the spectrum as a whole. Each of the frequencies is excited separately at a definite time interval. The duration of active periods does not exceed 2 or 3 hours.
