The 2024 HST COS G130M (1055 Å) spectrum of BZ Cam with line identifications. The spectrum is in red, and for convenience, the error is in gray. The spectrum has not been dereddened. All the narrow absorption lines are from the interstellar medium (ISM), mainly hydrogen molecular lines (H2) and iron lines (Fe II). The C III (1175 Å) line exhibits a prominent P Cygni profile. We also annotated the position of higher ionization species usually observed in disk-dominated CVs from S, Si, N, and P, but they cannot be identified in this spectrum.
