Query: Variable broad lines and outflow in the weak blazar PBC J2333.9-2343   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 M\'artir 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.
