Nine new Fast Radio Bursts were detected with the radio telescope BSA LPI of the Pushchino Radio Astronomy Observatory of the Lebedev Physical Institute at the frequency 111 MHz during processing of archival data of scintillation of radio source on inhomogeneities of interplanetary plasma in period from 2012 to 2018.

Earlier we reported on the detection of three fast radio bursts (ATel #11932). The main purpose of the work was the detection of fast radio bursts in galaxies M31 and M33 at this stage. As a result, three events were recorded in the direction of M33 (one of which is a repeating burst) and six events in the direction of M 31. The measure of the dispersion of pulses varies from 203pc/cm^3 to 1262pc/cm^3. Other parameters of the new Fast Radio Bursts can be viewed by clicking on the link at the end of the telegram.

Estimation of the dispersion measure suggests that the M33 and M31 galaxies are not the host for the registered pulses, and all the regions of occurrence of Fast Radio Bursts are much further.

Each pulse is visible only in one beam of multibeam diagram of BSA LPI. Since the width of the main lobe of the beam pattern of the BSA LPI radio telescope at half the level is ~ 30', these coordinates have comparable error.
