This galaxy is a member of the Virgo Cluster.
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB vL smbM to a resolvable nucleus."

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.5 mag galaxy. Their coded description reads BE,SLEL,BM.
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the Virgo Y group, a part of the Virgo II cloud complex, are NGC 4697, NGC 4699, NGC 4731, NGC 4856 & NGC 4939.

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.5M; 2.5' x 1.3' extent; bright, ENE-WSW-oriented oblong with brighter center and stellar nucleus; see photo at HAG-1; 9M star 10' due E; 9M star 10' SW."
Steve Coe, observing with a 13" f/5.6, notes: "Bright, large, elongated 1.8 X 1 in PA 45 at 100X, much brighter middle, almost stellar nucleus. Averted vision makes it grow in size."
Date: 7 6 1997
Small galaxy, bright nucleus. Haziness, no sharp edges, no spiral arms; patch of bright stars around.
8-inch f/10 SCT (EP: 1.25-inch 26mm SP 77x 41' fov; 1.25-inch 18mm SW 111x 36' fov) and 16-inch f/10 SCT (EP: 2-inch 32mm SW 127x 32arcmin; 2-inch 14mm UW 290x 17arcmin; 2-inch 8.8mm UW 462x 11' fov)
Large, relatively bright, round to oval slightly northeast and southwest hazy patch. The nucleus becomes slowly brighter to a well-defined bright nearly stellar nucleus (290x). Stars in an elongated formation play host to the galaxy towards the south and round it off beautifully. With averted vision I spot a few faint star embedded on the face of the galaxy (462x).
Observing site: Little Tycho Observatory
[12h 48m 36s, -5° 48' 0"] A very faint patch, without much brightening towards the center. Hard to see in tonight's light polluted, partly cloudy sky
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This galaxy almost takes the form of an out of focus mini baked bean that the shape of this diffuse object is slightly elongated and is oval-like in appearance.The central core of this galaxy is condensed and is visible as a fuzzy faint smudge of light being just seen at 75x.This galaxy measures 3.3'x 2.3'with P.A:WSW/ENE.
