The analysis of spectral variablity of BM Ori on JD 2446459.28 is given. The observed continuum corresponds to a spectral class F0 - F5. The spectrum suggests a high variability of the line He I λ4921 Å and strengthening of metal emission lines. Such a non-stationarity is proposed to be connected with the ejection of matter from a hot companion in a binary system.
