Search for Pulsed Radiation from the Magnetar SGR 1935+2154

A superluminous burst from the famous magnetar SGR 1935+2154 was recorded in the radio range in April 2020. The source discovered as early as 2014 was active only in X-rays. Radiation from SGR 1935+2154 was observed in the frequency range from 400 to 1400 MHz after recording powerful pulses. As a result of monitoring the magnetar during 2019—2021 with the LSA LPI radio telescope at the frequency of 111 MHz, a single pulse was detected with the following parameters: DM = 320 pc/cm 3 , fluence F = 300 mJy ms, scattering time τ = 340 ms, and flux peak density S = 140 mJy. The dynamic spectrum and pulse profile are presented in this paper.
