NGC 1877. See NGC 1874.
John Herschel recorded it as "a third and very faint nucleus of the nebular group at the southern extremity of the arc-formed cluster. From a figure of Jan 17, 1838." This grouping consists of NGC 1872, 1874, 1877 and NGC 1880.
Henize (Catalogues of Hydrogen Alpha Emission Stars and Nebulae in the Magellanic Clouds, Astrophysical Journal Supplement 2, 1956, p315) notes that his nebulae LH N 120-113A, 113B and 113E "form a chain of three small intense knots of nebulosity which, together, make up NGC 1877." Nebula 113A measures 21 x 29 arcseconds, whereas 113B and 113E appear as point-sources on the plates.
Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) group NGC 1874, 1876 and NGC 1877 together as a 2.4' x 2.4' group of "bright scattered stars in nebulosity."
The RNGC (Sulentic and Tifft 1973) notes that this is a cluster+nebulosity in the LMC.
