West (1977, Astron. Astrophys. Suppl. 27, 73-88) writes: "This galaxy, which is listed in the 'Reference Catalogue', shows several crossing, knotty arms on the ESO(B) and the Las Campanas IIIa-J plate. The knots may be traced to 1.5' from the centre. A somewhat diffuse spectrum .. gives a velocity of 1500 kms-1. This corresponds to an overall diameter of 21 kpc"
(Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy.
