  • Abstract
    The observations of variations of solar radio radiation on October 7, 2002 with a large radio telescope RT-22 SRI CrAO at wavelength 2.0, 2.3 and 3.5 cm revealed by a method of the wavelet-analysis a 78-sec delay of oscillations with period of 1760 sec at the longer wavelength of observation. Is shown that the delay can be a consequence of a compression wave propagation from height 5.5middot103 km up to height of 12middot103 km in chromosphere of the Sun, where the temperature increases from 114middot103 K up to 850middot103 K
