Abstract

A transient (LPA J0108+13) with repeated bursts was detected on the Large Phased Array (LPA) radio telescope at a central frequency of 110.4 MHz in the direction of the radio galaxy 3C 33. The flux density of bursts ranges from tens to hundreds of Jy, and the duration of the bursts is \( \simeq {\kern 1pt} 1{-} 4\) min. In daily observations, the total duration of which at the location of the transient exceeds 200 h in the observation interval of 2013‒2025, 6 bursts were found. The nature of the source could not be determined. We believe that a new type of transients has been discovered.
