Abstract (English):
We present a study of the multiwavelength variability of the blazar Ton 599 based on the radio-to--ray data covering the period of 1997-2024. The data are represented by the 1-22 GHz measurements from the SAO RAS RATAN-600 radio telescope, the 5 and 8 GHz data from the IAA RAS RT-32 telescopes, and the 37 GHz data from the RT-22 telescope of CrAO RAS. The optical measurements in the R-band were collected with the SAO RAS 1-m Zeiss-1000 and 0.5-m AS-500/2, SPbSU 0.4-m LX-200, and CrAO RAS 0.7-m AZT-8 telescopes. We also used the archive data at 230 GHz from the Submillimeter Array (SMA) and the -ray data in the 0.1-100 GeV band from the Fermi-LAT point source catalogue 4FGL-DR2. The blazar exhibits extreme variability properties with a variability index varying from 0.47 to 0.98. A characteristic feature of the light curves is the presence of double and triple flares with different spectral properties. A significant correlation ($\geq 2\sigma$) between the radio, optical, and -ray bands is found with time delays from 0 to 365 days. The L-S periodograms show the significant peaks ($>3\sigma$) related to periods of 2.4-3.9 years, which coincides with global oscillations obtained earlier on the time scale of 1987-2010.
