ω Ori is a rapidly rotating B2IIIe star with known spectral variability. We applied a frequency analysis to the MuSiCoS (MUlti Site Continuous Spectroscopy) campaign 1998-dataset to search for line-profile variations (Ipv). Variability was found in all studied spectral lines and interpreted as due to non-radial pulsations (NRP).
