The observed lines of hydrogen and another
strong lines in the spectrum of RM_1-667 (red region of spectra, 5900-7100 Å, spectral type is K7 I) are discussed. Analysis of these lines indicates the presence of mass outflow from the star at a significant velocity.
Using the iron lines and the model atmospheres of supergiants(Teff = 3750 K – 4300 K) of the Kurucz‘ grid, we obtained the iron abundance lg ε (Fe) = 6.75-7.08, which
is equivalent to [Fe/H] equal -0.75 to -0.42.
