A spectroscopic comparison of the two stars yields a spectral type for HD 97152 of WC7 + O7 V. Radial velocity measurements of this star indicate a double-line circular orbit with period 7d.886 ± 0d.003 and masses M(W) sin3 i = 3.6 ± 0.3 Msun and M(O) sin3 i = 6.1 ± 0.5 Msun. The mass ratio, M(W)/M(O) = 0.59 ± 0.02, falls in the range of other known galactic WR + OB binaries. Intermediate-band photoelectric photometry shows low-amplitude, sinusoidal magnitude variations with the same period for a filter which straddles the strong emission feature at 4650 Å whose Doppler motion alone can explain the magnitude variation. The continuum is constant to within ±0.005 mag. Taking M(O7 V) = 29 Msun, we get an orbital inclination of 36°.5 and M(W) = 17.5 Msun, like the minimum mass for the WC8 component of γ2 Velorum. Significant radial velocity variations in HD 156385 are not detected.
