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)

Synonyms: H V-008

Hartung notes: "This remarkable object is very long and narrow, about 12' x 1.5' in good conditions; it is an edgewise spiral in pa 100 deg . . with 15cm it looks long and narrow, but faint."

Published comments

Arp (1966)

Together with NGC 3623 and NGC 3627 it is listed as No. 317 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.)

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 10.5 mag galaxy. Their coded description reads EON,BM,EQDKLN-WD.

Sandage & Tammann (1975)

Sandage, A. & Tammann, G. A. (1975) Steps toward the Hubble constant. V - The Hubble constant from nearby galaxies and the regularity of the local velocity field. ApJ, 196, 313-328. [1975ApJ...196..313S]

Sandage and Tammann (1975, Astrophysical Journal, 196, 313-328) includes this galaxy in the Leo Group. Members include NGC 3338, NGC 3351, NGC 3368, NGC 3377, NGC 3379, NGC 3384, NGC 3389, NGC 3412, NGC 3489, NGC 3593, NGC 3596, NGC 3605, NGC 3607, NGC 3608, NGC 3623, NGC 3626, NGC 3627, NGC 3628, NGC 3686 & NGC 3810.

NGC 3628 Donald J. Ware:"Large, 10'x2', and oriented northwest-southeast, this object is faint overall, but averted vision shows a spindle-like shape with hints of a dust lane on the southwest side. A very interesting galaxy."

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.

M66 Group: This is the well-known compact triplet of spirals including M65 (NGC 3623), M66 (NGC 3627) and NGC 3628 together with several outlying systems including probably NGC 3593, NGC 3596, and NGC 3666, and possibly NGC 3485, NGC 3489, NGC 3506 and NGC 3547.

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.3M; 12' x 2' extent; spindle shaped; axis oriented ESE-WNW; makes isoceles triangle with M-65 and M-66; !good supernova prospect!."

Location: Alldays

12-inch f/10 SCT (218x 346x)

NGC 3268 is by far the larger and more outstanding galaxy in this field with various other galaxies. The quite round haze show little detail with a slightly hazy edge. On NGC 3268 western edge the very small spec of haze indicate NGC 3267 which I could see with quite ease.

(no date)

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

Very elongated and with a ruff texture, may be dark areas. Very much brighter to the middle. I try the IC Galaxies 2725&6 between on way to M66 & M65. Suspect it.

Telescope: C-8

[11h 20m 18s, 13 36m 0s] A faint streak in the sky, like M 65 and M 66, but considerably fainter.
