Also catalogued as VV 621, this galaxy is described by Barbieri et al. from careful examination of photographic plates as follows: "One very bright arc with two very bright condensations; other faint more diffuse arcs with branchings and discontinuities ... size 90" x 50"."
p 565: "3. Interesting objects. We briefly call attention to interesting cases … One peculiar spiral with one very bright arc or arm, the other arm being inconspicuous."
p 567, Table 2: Photographic Observations, apparent major axis in arcseconds = 90.
The RNGC (Sulentic and Tifft 1973) notes that this is a 13.5 mag galaxy. Their coded description reads S),PEC,KNY,DKPCHS LG APP.
