Abstract

This paper presents the result of the search for pulses from the fast radio burst FRB 20220912A on the antenna of the BSA FIAN at a frequency of 111 MHz during the period of activity in October-November 2022. As a result of observations, pulses were recorded on October 18, 30 and November 12 with a dispersion measure of \((220 \pm 10)\) pc/cm³ and a peak flux density of 626 Jy, 354 Jy, and 203 Jy, respectively. The registration of the FRB 20220912A radio burst on the FAST radio telescope on October 28 in the frequency range of 1–1.5 GHz is also reported. The data at other frequencies are analyzed, the dependence of the pulse width on the frequency \({{t}_{s}} \sim {{f}^{{ - 2}}}\) is obtained.
