PBC J2333.9-2343 is a peculiar active nucleus with two giant radio lobes and a weak blazar-like nucleus at their center .
In the present work we show new optical , UV , and X-ray data taken from the San Pedro Mártir telescope , the New Technology Telescope , NTT/EFOSC2 , and the Swift /XRT satellite .
The source is highly variable at all frequencies , in particular the strongest variations are found in the broad H \alpha component with a flux increase of 61 \pm 4 per cent between 2009 and 2016 , following the X-ray flux increase of 62 \pm 6 per cent between 2010 and 2016 .
We also detected a broad H \beta component in 2016 , making the optical classification change from type 1.9 to type 1.8 in one year .
We have also detected a broad component of the [ OIII ] \lambda 5007 line , which is blue-shifted and of high velocity , suggesting an origin from a highly disturbed medium , possibly an outflow .
The line flux variability and broad widths are indicative of a jet that is , at least in part , responsible for the ionization of the BLR and NLR .
