Complete optical spectra of R 40 taken from 2005 until 2016 with FEROS. The spectra are radial velocity corrected, but without telluric correction. It is possible to see the changing from a late B-type or early A-type to a late-F spectrum owing to the newly identified eruption. The spectrum of HD 54605 (F8Iab) is also shown for comparison. The identification of the lines, based on Moore (1945), Lambert et al. (1996), Castro et al. (1997), and Hill et al. (2002) are also provided.
