Hα profiles of SALT observations of the optical counterpart of 1eRASS J054422.3−672729 between 5 and 23 November 2023 shifted to the rest-frame of the LMC. The black line shows the data, the blue line shows the best-fit spectrum using a wide absorption line and a narrow emission line feature, and the dashed red line indicates the rest-frame wavelength of Hα. Between individual observations lies a shift of 1.5 for the normalised flux for readability. The equivalent widths and radial velocities are given for the narrow absorption line.
