Abstract

In this paper, the results of observations of the XINS 1308.6+2127 (RX J1308.6+2127, RBS 1223) magnetar at a frequency of 111 MHz have been presented. To search for pulsed emission, data from the BSA radio telescope at the Lebedev Physical Institute, which were recorded in the mode of 32 frequency channels with a time resolution of 0.0125 s, and in a receiving band of 2.5 MHz, have been used. As a result of data processing in the period of 2012 \( - \) 2023, emission at the specified frequency has been detected. The following pulse parameters were measured in the study: peak flux density of 0.28 ± 0.03 Jy, 10%-width of W10 = 0.2 s, fluence of 55 Jy ms, and dispersion measure of 3.7 ± 0.5 pc/cm3.
