Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/yivumoo/public_html/show_object.php on line 167

Historical observations

William Herschel (c.1784)

Published comments

Burnham's Celestial Handbook

Burnham calls this a 12.6 mag spiral in Cetus, 2.7' x 0.8', "pretty bright, pretty large, slightly elongated."

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads EL,DIF,SBM,DKLNS DIF COM 1'SP.

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)

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 615 measures 2.7' x 0.8' and is about v-mag 11.5

Ancient City Astron.Club (1980)

described as "very elusive, small, circular and evenly bright. Best with averted visiion applied. Situated near a bright field star. 6-inch, 48x."

Tom Lorenzin

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 4'x 1.5' extent; soft, ellipse-shaped, unresolved, many-armed spiral; see photo at HAG-22; EL GAL N636 (12.5M; 1.5'x 1' extent) is 1 degree to ESE; EL GAL N596 is 35' to NW just W of 6M star."

Steve Coe

Steve Coe, using a 13" f/5.6, notes: "Pretty bright, pretty small, somewhat elongated, much brighter middle."

15cm - mod br, circ. *ar nuc w/o core, but nice halo.

25cm - lies 5' ENE of m9 *. seems elong either in pa0 or pa150, seeming to alternate btwn. core elong too, perhaps w/gap to S side. halo 1'.5x0'.5.

30cm - easy 6' ENE of m8.5 *. mod concen w/sub*ar nuc. halo 2'x1' in pa175, not as concen as N596. *ar nuc seems to be N of center.
