This large complex is composed of four HII regions in the direction of the northern Auriga OB1 association. While seemingly separated in appearance, members of the Sh2-232 complex all belong to a single giant molecular cloud. The constellation Auriga is located in the "Galactic Anticenter" a region that hosts a number of massive molecular cloud complexes. The dominant region of star formation is centered around the Sh2-232 complex.

5,870 ly distant
