  We report on spectroscopic and photometric observations of the S-type Mira
V667 Cas and the carbon star Mira OR Cep recorded during one pulsation cycle of
each star in 2022. Spectra are calibrated in absolute flux using concurrent
photometry. We present measurements of V and Ic magnitudes and V-Ic colour
index, classify spectra in the revised MK system and investigate how absolute
flux in the H-alpha to H-delta emission lines varies with pulsation phase for
each star.
