HD 34626, also known as MZ Aurigae, is an unusual variable star in the northern constellation of Auriga. It varies in brightness by 0.1 magnitude over time scales of 8 to 12 hours, but these variations are not periodic. This indicates the variability is not caused by ellipsoidal effects, and the nature of the variability remains unknown. It is a Be star and is rotating rapidly.[6]
