IC 2177 is a region of nebulosity that lies along the border between Monoceros and Canis Major. It’s a roughly circular H II region centered on the Be star HD 53367.

The name Seagull Nebula is sometimes applied by amateur astronomers to this emission region, although it more properly includes the neighboring regions of star clusters, dust clouds and reflection nebulae. This
