Abstract
The search for rotating radio transients (RRATs) was carried out at a frequency of 111 MHz, as daily observations carried out on the Large Phased Array (LPA) radio telescope at declinations of −9° < δ < +42°. Overall, 19 new RRATs were discovered for dispersion measures (DMs) from 2.5 to 72.6 pc cm−3. Estimates of the periods were obtained for three RRATs, with two of them (J0408+28; J0440+35) located at distances of 134 and 136 pc from Sun, placing them among the closest of all known RRATs.
