Variability of the flux densities of radio sources on timescales shorter than a month

Results of a study of the variability of radio sources on timescales of 3–30 days based on six sets of daily observations on the RATAN-600 radio telescope with durations from 53 to 103 days at six frequencies from 0.97 to 21.7 GHz are reported. The variability timescales and spectra determined from the analysis of light curves, structure functions, and autocorrelation functions for 11 radio sources from a complete sample in the declination range 4°–6° (B1950) are presented.
