We present the investigation of PSR J0653+8051 at frequency 111 MHz using Large Phase Array. This pulsar shows three components in the range 102-4850 MHz. We detected a few dozen of very strong pulses exceeding the amplitude of the mean profile more 110. Usually this pulsar demonstrates very weak signal on the level 3 sigma in mean profile. The detail analysis showed that all strong pulses with S/n ratio 4-20 sigma arrived on the longitude of the central component only. This eect is very seldom, because we detected such giant components only one day from more than two hundred days of observations.
