Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB S."
(Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads E,SLEL,BM.

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.4M; 1.6' x 0.9' extent; stellar nucleus; 14M SP GAL N3377a (1' diameter) is a few minutes to NE; very, very faint; both are !good supernova prospects! SP GAL N3367 is 20' to SW."

[10h 47m 42s, 13° 59m 0s] Bright center, elongated envelope. Lovely galaxy. Spiral, Sb or Sc? (E5: Burnham!)
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's circular like shape is seen as a grayish smudge of faint light and is unimpressive with no detailed like structure.This galaxy measures 3.3'* 1.1'.Right from the nucleus of this galaxy the light of this galaxy grows brighter compared to the far outskirts of this galaxy.
