This rich collection of predominantly reflection and sparse emission nebulosity exists in the western part of a vast star forming region known as the Mon R 2 association. The "R" designation stands for reflection and indicates an association of stars illuminating reflection nebulae. Most of the members of Mon R 2 are type B stars located along an east-west line stretching across 2 degrees of the winter sky, situated about 8 degrees east of the Orion Nebula. The Mon R 2 association resides at a distance of 830 pc and formed about 6 to 10 million years ago along the edge of the  Mon R2 molecular cloud.
