We have obtained a high resolution red spectrum of the WN5 star EZ CMa
(HD 50896) in the
framework of a campaign of multiwavelength monitoring of
a number of hot massive stars in the optical
and ultraviolet (MEGA, cf. St-Louis et al. 1995).
The spectrum was collected at phase
0.557 of the 3.766 day periodicity of the star (Lamontagne et al. 1986).
The strong 656 nm He II feature (Fig. 1) is more extended than
the instrumental spectral range (about
1600 km s-1),
so that we could only give a lower limit of the equivalent width.
The emission presents a flat maximum
and, on the red side, an emission hump at 658.06 nm.
