HD 151932, also known as WR 78, is a Wolf-Rayet star located in the constellation Scorpius, close to the galactic plane.

[10] Despite being a blue-colored Wolf-Rayet star, it is extremely reddened by interstellar extinction, so its apparent magnitude is brighter for longer-wavelength passbands.

Like most extremely massive stars, HD 151932 is losing mass via its stellar wind.

[11] A periodic shift in the spectrum with a period of 3.3 days (implying it is a spectroscopic binary) has been noticed, but it may be spurious; the star appears to be a single star but may be orbiting face-on and/or with a lower-mass companion.

[8] Related to this is the fact that the Si IV line varies irregularly in radial velocity, the nature of which is largely unknown.
