High-resolution optical spectra of Mira covering the resonance lines of Al i and Ti i. The date of observations and the corresponding phase and visual magnitude are specified in the upper right corner of each panel. All spectra were normalized with high-order polynomials. The pseudo-continuum in this spectral region is dominated by broad wings of the Ca ii doublet and the normalization partially removed its absorption. The normalization was optimised to better illustrate the shape of the Al i lines and to limit the scale of the figure. The imperfect normalization affects the apparent intensity ratio of the two lines of Al i. Some spectra were smoothed. Identification labels are shown for selected features at their approximate locations.
