William Herschel (c.1784)
Synonyms: H V-045
Discovered in 1789 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, iF, E nearly in merdian, LBN with faint branches, 7 or 8' long, 5 or 6' broad."
Published comments

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads S,EL,INTDKLNSTR, MUCH PERIPH FILDIF SSTR.
Sandage, A. et al. (1975) Galaxies and the Universe
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the Ursa Major I (N) Group are NGC 3992, NGC 3953, NGC 3631, NGC 3898 & NGC 3718.
Modern observations
Tom Lorenzin
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.1M; 6' x 3' extent; fairly bright, NE-SW-oriented mass with brighter center and non-stellar nucleus; looks like distant globular cluster; 80' due S of Phecda (Gamma UMA); 40' to SW is faint SP GAL N3917 (12.2M; 3' x 1' extent), a slashy glow; both are !good supernova prospects!."

[11h 53m 48s, 52° 20m 0s] A faint, uniform smudge. The transparency was not good tonight. Heavy dew. This might have looked better in darker skies.
