Historical observations
William Herschel (c.1784)
Synonyms: H II-004
Discovered in 1783 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pB pS R mbM, resembling a telescopic comet."
Birr Castle/Lord Rosse
(72-inch f/8.8 speculum telescope) "B, S, R nucleus, a star preceding and another north."
Published comments
Burnham's Celestial Handbook
Burnham calls this a 12.2 mag elliptical in Cetus, 1' x 0.9', "pretty bright, round, brighter in the middle; 6th mag star 12' following."
Sulentic & Tifft (1973)
(Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads E,R,BM.
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 Cetus II Cloud includes the NGC 584 & NGC 681 Groups. The five brightest members of the Cetus II Cloud are NGC 720, NGC 584, NGC 779, NGC 596 & NGC 615.

de Vaucouleurs, G. (1975) Nearby groups of galaxies. In: Kuiper, G. (ed) Stars and Stellar Systems. Volume 9: Galaxies and the Universe. Chapter 14, p557.
Includes NGC 584 and NGC 681 groups.
Brightest members: NGC 720 ( B(0) = 11.47), NGC 584 ( B(0) = 11.71), NGC 779 ( B(0) = 12.20), NGC 596 ( B(0) = 12.31), NGC 615 ( B(0) = 12.51).
Modern observations
Walter Scott Houston
Notes that this is one of a line of three galaxies southeast of NGC 584. These three are NGC 596, NGC 615 & NGC 636. NGC 596 is an elliptical, 0.6' x 0.5' and has a visual mag of 11.5.
Ancient City Astron.Club (1980)
described as "very small circular object with a fairly bright nucleus, dimming towards the outer edges. 8-inch, 48x."
Tom Lorenzin
Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 3.5'x 2.2' extent; bright and round with brighter center; 6M SAO 129371 is the bright star 15' due E."
Steve Coe
Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty small, round, much brighter middle at 100X. Has a stellar core at 135X in moments of good seeing."
