Observations of the total radio flux of the Sun are presented for the period 1962-1986, ciovering two 11-year cycles of solar activity, -i.e. nos 20 and 21. Daily averages of the radio fluxes for the period in question are used for graphical and numerical representation. The minimum values fo the total radio flux of the Sun of wavelength 115 cm (260 MHz), corresponding to the solar activity minima in 1964, 1976 and 1986 are given.
