The search for neutrino bursts at the Baksan Underground Scintillation Telescope began in the middle of 1980. Two parts of the setup with a total mass of 240 t are used as the target. The actual observational time accumulated in the period from June 30, 1980, to December 31, 2017, is 32.1 years. No neutrino burst candidate events were detected, yielding the following upper bound for the mean rate of core-collapse supernovas in the Milky Way: 0.072 yr⁻¹ (90% CL).
