NGC 2363 is a star-forming region within the
galaxyNGC 2366. It has been used as an example of such a
region with a very low metallicity but some determinations
have found its metallicity merely moderately low.
Note that the term NGC 2363 is ambiguous despite its use in
published research: there is not complete agreement on which
currently-viewed object corresponds to the
New General Catalogue's (NGC's) object number 2363.
The catalog itself, published in 1888, lists number 2363 as an
object with 1860-epochcoordinates
071352+691857, with an inconclusive description.
One of the candidate-objects is the above-described
SF region (which is also sometimes classified as a galaxy
of some sort), and the other is NGC 2366's center, generally
classified as an active galactic nucleus (AGN).
