Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "very brilliant, iR, vgmbM."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vB, R, vsvmbM, 2.5' long; resolvable to left eye."

! A curious and complex form of spiral. The N is vB and alm.stell. From it project two bright, slightly curved, spiral arms in PA 55deg and total length 40deg [sic?]; these merge into a pB oval disc with a sharp edge, 1'x40'', E 50deg in which are dark lanes and indications of spiral structure; outside this is a vF slightly irr. oval disc 3.5'x2', E 45deg. The central portions of this object should be bright enough for a determination of its radial velocity to be made.
This galaxy appears on page 16 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).
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.
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads SO),SLEL,SBM.
Two supernovae erupted in this galaxy; 1948 (17.5p), 1983 (14.0pg)

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.3M; 3' x 2' extent; bright, NE-SW-oriented oblong with brighter center and stellar core; see photo at HAG-16."
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, round, much brighter in the middle at 100X. This galaxy has a high surface brightness and averted vision makes it grow in size."
Very bright nucleus in middle.
8-inch f/10 SCT (EP: 1.25-inch 26mm SP 77x 41' fov; 1.25-inch 18mm SW 111x 36' fov)
Large, bright galaxy, getting brighter to a much brighter nucleus. Slightly oval, northwest to southeast it displays a soft haziness that mingles with the darkness surrounding it. Situated between a square of four stars, along with multiple faint stars that surrounds this breathtaking galaxy.
1998-04-27/28, 11x80 tripod-mounted binoculars, Die Boord. Seeing average, transparency average, dew. "Not found."
Observing site: Little Bennett Regional Park
[12h 49m 0s, -8° 40' 0"] Looks like a distant globular. Probably an E0. Bright. (Burnham: Sa/Sb, Looks like Sa to me on WikiSky.)
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 has the shape of a tiny mealie and that this very faint object is seen as an out of focus halo of oval light.The central core is clearly visible as a pale glow of grayish yellow light gently glowing in a field barren with a few 9th to 10th magnitude stars.I also noticed that the nucleus of this galaxy is moderately compact.This galaxy measures 3.1'x 2.3'.
