This object was discovered in 1978 and described as "diffuse object of uncertain nature," with dimension and brightness measured as given above, described as a circular object. Suspicion was given that this might be a globular cluster similar to Liller 1 or Terzan 2 (Terzan et.al 1980). It was also listed as presumable globular cluster in Webbink (1985).

It was later identified as a spiral galaxy of type Sc, LEDA 140767.
