This source has previously shown intense dips in the optical lightcurve, a phenomena that has been linked to the existence of a \"unique toroidal structure\" in the inner region of the disc, seen at a high inclination. Our observations, carried out by the Neil Gehrels Swift and NuSTAR X-ray observatories, do not show the presence of intense dips in the optical light curves. We find that the X-ray light curves do not show any features that would straightforwardly support a","authors_text":"A. Bahramian, Aru Beri, B.E. Tetarenko, Diego Altamirano, G.R. Sivakoff, John A.
