Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, pL, R, vgmbM."
Burnham calls it a 12.7. mag elliptical galaxy in Canes Venatici, measuring 0.9' x 0.8' , which he describes as "considerably bright, pretty large, round and pretty suddenly much brighter to the middle."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads E,R,BM,DKLN SUSP.
This galaxy appears on page 8 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).
