Historical observations

William Herschel (c.1784)

Synonyms: H I-209

Published comments

Burnham's Celestial Handbook

Burnham calls it a 12.3 mag spiral galaxy in Canes Venatici, measuring 2.5' x 0.6', which is considerably bright, pretty large, pretty much elongated, pretty suddenly brighter in the middle, lens-shaped.


A supernova erupted in this galaxy in 1983 (14.5p)

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads DIF,SPN,BM.

Modern observations

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.3M; 2.5' x 0.5' extent; soft, NW-SE-oriented slash with brighter center; 8M star 15' due N; good supernova prospect."

12-inch f/10 SCT (95x/52.8′, 218x/23.1′)

This galaxy could be just be a miniature of M106 as seen with 12" S/C 95x. Soft, small smear of light in a NW-SE direction. Slowly brightens to a slightly brighter nucleus 12" S/C 218x. It also corresponds with the size of 4' in length towards my field of view 23.1 FOV.
