Pulse energy distribution for RRAT J0139+33 according to observations at the frequency 111 MHz.

Using five year monitoring observations, we did a blind search for pulses for rotating radio transient (RRAT) J0139+33 and PSR B0320+39. At the interval \pm 1.5m of the time corresponding to the source passing through the meridian, we detected 39377 individual pulses for the pulsar B0320+39 and 1013 pulses for RRAT J0139+33. The share of registered pulses from the total number of observed periods for the pulsar B0320+39 is 74%, and for the transient J0139+33 it is 0.42%. Signal-to-noise ratio (S/N) for the strongest registered pulses is approximately equal to: S/N = 262 (for B0320+39) and S/N = 154 (for J0139+33). Distributions of the number of detected pulses in S/N units for the pulsar and for the rotating transient are obtained. The distributions could be approximated with a lognormal and power dependencies. For B0320+39 pulsar, the dependence is lognormal, it turns into a power dependence at high values of S/N, and for RRAT J0139+33, the distribution of pulses by energy is described by a broken (bimodal) power dependence with an exponent of about 0.4 and 1.8 (S/N 19). We have not detected regular (pulsar) emission of J0139+33. Analysis of the obtained data suggests that RRAT J0139+33 is a pulsar with giant pulses.
