Published comments

Burnham's Celestial Handbook

Burnham calls it a 13th mag spiral galaxy in Canes Venatici, measuring 1.4' x 1.0' , which he describes as "faint, pretty small, very slightly elongated and a little brighter in the middle."


A supernova erupted in this galaxy in 1977 (14.0p)

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 13.0 mag galaxy. Their coded description reads SB,IRRDIFHALO.

Modern observations

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "13M; 1.5'x 1' extent; pretty little faint blob with 14M stellar nucleus; just S of a 7M star; 45' to NNE is N5407 (13M; 1'x 0.5' extent) with a 14M stellar nucleus; it's located inside a small group of five 9-11M stars, at the NE corner of the group; oblong with axis oriented N-S, and a 14M star 1' due N of the core."
