The LIGO/Virgo collaborations have reported the results of their searches for gravitational-waves from the first half of their third observing run. 39 events were added to the first Gravitational-Wave Transient Catalog (GWTC-1), reaching the total number of 50. Thus, an additional search for counterparts is necessary. The data from Baksan Underground Scintillation Telescope (BUST) are used to search for neutrino counterparts. The BUST detections of muons from the lower hemisphere in the zenith angles >100° are used. The angular uncertainty of muon neutrinos and antineutrinos from the lower hemisphere is ~5°. The energy threshold is 1 GeV. If no counterparts found the integral fluxes of muon neutrinos and antineutrinos are calculated. This work presents the description of data processing and the limits on integral fluxes from the gravitational-wave localization regions.
