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.

Historical observations

William Herschel (c.1784)

5. The nearer groups within 10 megaparsecs

G4. NGC 5128 Group

Brightest members: 5236,5128,4945,5102,5068,5253.

Several large southern galaxies having low velocities may form a loose group or chain centred on NGC 5128, 4945, 5102, 5236 and NGC 5253 and possibly NGC 5068. Two (NGC 5102 and perhaps NGC 5128=CenA) are lenticulars, three are late-type spirals Sc-Scd and one (NGC 5253) is peculiar, possibly an I0 irregular (the BGC classificaion Imp is incorrect). The overall length of the chain is 30° = 2.1Mpc or 20° = 1.4 Mpc (excluding NGC 5068 which has the highest velocity). ... Even if this chain does not form a physical (bound) group, it is useful to obtain some estimate of the distance of NGC 5128.

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads SBC,VDIF,BM TOBAR,PD KNOTTY.

Sandage and Tammann (1975, Astrophysical Journal, 196, 313-328) includes this galaxy in the NGC 5128 Group. Members include NGC 4945, NGC 5068, NGC 5102, NGC 5128 & NGC 5236.

Included in the CCD-atlas of Ryder S.D. & Dopita M.A. (1993) "An H-alpha Atlas of Nearby Southern Spiral Galaxies" Astrophys.J.Suppl. 88, 415. They note: "Here is yet another example of how lopsided the H II region distribution in late-type spirals can be, even those exhibiting well-organized spiral structure. A number of giant H II region complexes to the west are visible even in blue light photographs, but only two such objects are found in the eastern arms."

Modern observations

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.6M; 6' x 5.5' extent; fairly large, faint, not quite round fuzz ball with brighter center; !good supernova prospect! EL GAL N5087 (12.4M; 50" x 30" extent) small, centerless fuzzy patch 30' to NE with 9M star 7' to NW."

ASSA-DSO - Report H

This is a real faint, roundish structure with no hint of a core. Gaseous structure, like cottonwool. A few faint stars to the edge of the field.

This is a really faint, large roundish structure with a very dim small nucleus. Busy extended gaseous surroundings. A few faint stars to the edge of the field.

8-inch f/10 SCT (EP: 1.25-inch 26mm SP 77x 41' fov; 1.25-inch 18mm SW 111x 36' fov)

This is a really faint, large round puff of light, with a very soft small nucleus. Very hazy outer envelope can be detected with careful observation. Busy extended gaseous surroundings. Few stars surround this galaxy, which is situated in a bare star-field.

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

Instrument:12-inch Dobsonian.

This galaxy has a circular patch of faint light which looks like an out of focus mist in the dark and that the galactic nucleus of this galaxy is strongly condensed.Around the regions of this galaxy there are plenty of dark regions being noticed.This galaxy measures 9.1'x 7'.Chart No:464,NSOG,Vol.2.
