Discovered in 1787 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, S, R, resolvable, mbM."
Burnham calls it a 13.1 mag spiral galaxy in Bootes, measuring 1.1' x 0.9', which is pretty bright, small, round and suddenly much brighter in the middle.
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads R,SLDIF,SMBM,HISB DKLNS SUSP.
Steve Coe, using a 13" f/5.6, notes: "Pretty faint, pretty small, round, somewhat brighter middle with a stellar nucleus at 100X. There is a 13th mag star about 10" south of the core."
