Variation of pulsar signal received with the PL612 as an indicator of the ionosphere dynamics

PL612, one of the three Polish LOFAR stations is fully operational in the International LOFAR Telescope (ILT) since beginning of 2016. In second half of 2016 we have also started a pulsar observational projects in the local mode using the Baldy LOFAR station. In this paper we shortly describe a new project which focuses on the simultaneous observation of pulsars and the TEC parameter towards them in the sky.
