Spectrum of Wray 15−0751 obtained with the HARPS instrument on 17 February 2008, more than one year into the most recent S Dor phase, normalized to the continuum. The vast majority of the lines are due to FeI. The MgI feature at 4481 Å is rather prominent while the neighbouring HeI line at 4471 Å is altogether absent. Other HeI and HeII lines in this wavelength range are also not present.
