Temporal changes in selected atomic line profiles of V838 Mon. Keck/HIRES spectra from 2005 (Kamiński et al. 2009) are shown in purple, VLT/UVES spectra from 2009 in green (Tylenda et al. 2011b), VLT/X-shooter spectra from 2012 inorange, and SALT/HRS spectra from 2020 in gray. The spectra were arbitrarily scaled to show changes in the four labeled atomic lines. The vertical lines mark the velocity of the SiO maser (or the supposed stellar systemic velocity; 54 km s⁻¹ LSR or 71 km s⁻¹ in the heliocentric frame) and the position of the turnover in the inverse P-Cyg profile of Hα (37 km s⁻¹ heliocentric).
