Mode switching characteristics of PSR B0329+54 at 150 MHz

We present the results of 60 hours of observations of PSR B0329+54 with the LOFAR PL-612 station located in Baldy near Olsztyn, Poland and managed by University of Warmia and Mazury in Olsztyn (UWM). Observations were conducted in August/September 2016 and in May and August 2017 using the HBA antennas, at the central frequency of about 140 MHz, and they were conducted in form of six 10-hour semi-continuous observing sessions. The main goal of the analysis was the study of the mode switching phenomenon in this pulsar, and our results show that at this frequency the abnormal profile mode is present only for about 12.6% of time on average, which is lower than for the analysis of a very large set of 1.5 GHz observations performed at Urumqi observatory in 2011. Also worth mentioning is the fact, that the results shown in this paper also demonstrate the first scientific output concerning pulsar observations with the PL-612 station.
