V352 Aurigae is a variable star in the northern constellation of Auriga. According to the Bortle scale, an apparent magnitude of 6.14 means that it is faintly visible to the naked eye from dark rural skies. It is a variable of Delta Scuti-type, which suggests that the variability is caused by the rotation of the host star in combination with localized regions of activity.[7]
