Located in the southwestern part of Vulpecula, this small emission nebula is observed about 0.7 degrees northwest of the open cluster Cr399, known by the nickname "Coat hanger". It has an apparent diameter of only about 2 arc minutes, and its internal structure appears indistinct. Due to the unknown distance, its actual size remains undetermined.
