Historical observations

Dunlop, James (1828)

Dunlop, J. (1828) A Catalogue of Nebulae and Clusters of Stars in the Southern Hemisphere, Observed at Paramatta in New South Wales. Phil. Trans. Roy. Soc., 118, 113-151. [1828RSPT..118..113D]

James Dunlop discovered this galaxy from Paramatta, New South Wales, and included it as No. 206 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a faint ill-defined nebula, rather extended in the direction of the meridian, with several exceedingly minute stars in it."

John Herschel

Sir John Herschel observed it at the Cape of Good Hope with an 18-inch f/13 speculum telescope, describing it as "pretty bright; irregularly round or slightly elongated; very large; very gradually brighter in the middle; resolvable; 3' diameter."

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.

p 590: "The present data on nearby groups may nevertheless help to answer the simpler question:Are there isolated galaxies? ... out of the 60 galaxies in this objectively selected sample, only eight have not been associated with one of the 55 nearby groups, viz. NGC 404, NGC 1313, NGC 2903, NGC 3109, NGC 3521, NGC 6744, NGC 6946 & IC 5152. In addition there is a possibility that a few galaxies, such as NGC 1316, NGC 4594, NGC 4826 are not really members of the groups (For I, Vir Y, CVn I) to which they have been tentatively assigned. Furthermore, the reality of the NGC 5128 chain as a physical unit may be questionable; but then it is difficult to know where to stop in this 'dismemberment' of loose groups, and the local outcome of an overconservative attitude would be to exclude from consideration all but a few rich clusters and dense groups... on the other hand, several of the eight supposedly isolated galaxies might yupon further investigation turn out to be members of some of the nearer groups; in particular, NGC 404, NGC 3109 and IC 1512 should be examined for possible membership in the Local Group. Other (more remote) possibilities are NGC 1569, IC 342 and perhaps some heavily obscured systems as yet unrecognized. For example, IC 10, although long suspected, was only recently established as a Local Group member (Roberts 1962, de Vaucouleurs and Ables 1965). ... to the writer's knowledge, NGC 1313 and NGC 6744 in the southern sky, and probably NGC 2903 and NGC 6946 in the northern sky, are truly isolated galaxies not associated with any nearby group, although both are in the larger Local Supercluster."

Ryder & Dopita (1993)

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: "NGC 1313 represents an interesting transition object between the late-type spirals and the Magellanic Irregulars. Coincidentally, it sits midway between the Large and Small Magellanic Clouds, but at a distance of about 4.5Mpc . . The most luminous H II regions outline the two main arms and bar, with a break near the optical nucleus. Isolated patches of star formation are found to the southwest, as well as beyond the tip of the northern arm."

03 18 15.5 -66 29 51

V = 8.7; Size 9.1x6.9; Surf Br = 13.1; PA = 39d

24" (4/4/08): this was the first object I decided to take a look at in the 24" f/3.7 as it was probably the brightest remaining galaxy that I had not observed. I was amazed to find a striking, two-armed barred spiral with obvious bright HII knots in the arms! At 200x the main body of the galax appeared as a bright oval or wide bar ~4.5'x3.5' oriented SSW-NNE with a central bulge. Emerging from the SSW end is a relatively short arm that hooks towards the NW.

Embedded with this extension is a brighter elongated HII knot, ~30"x20". A mag 15 star is west of the NW end of this arm. Just east of the NNE end of the main bar is a brighter HII knot, ~30"x15", oriented E-W. A faint star (or stellar knot) is less than 1' NW. This bright HII region is embedded in a diffuse arm that curves gently ESE from the N end of the bar. After the bright knot, this extension dims but ends at a third bright knot, ~15" diameter, that is isolated the end of this arm (nearly due E of of the core). This object is on a small list of Starburst galaxies with young globular-cluster-like clusters (SSC's).

Telescope: Meade 8" 18mm (36'fov) and 26mm (40'fov)

Sky conditions: Not very good.

Bright, large, about 8 arc minutes in size and little elongated (north to south). Two stars to the northeast, a star west, and another star the brightest, about 5 arc minutes to the south.

12-inch f/10 SCT (EP: 2-inch 40mm SW 76x 53' fov; 2-inch 14mm UW 218x 23' fov; 2-inch 8.8mm UW 346x 15' fov)

This bright and large haze is slightly irregular in a northeast to southwest direction. The northeast flimsy end is noticeable fainter than the southwest tip. No trace of a nucleus, just two stars situated at the eastern and western edge (218x). A lovely bright white star of about 6th magnitude is situated on the edge of the field of view.
