ONE CHART AWAY from the Large Magellanic Cloud, we find a smattering of small galaxies and a distant globular cluster.

FEATURED OBJECTS: NGC 1313, NGC 1466, NGC 1511, PK284-39.01, NGC 1534.

NGC 1313
ESO082-G011

Galaxy

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."

h: "pB, iR or slightly elongated; vL, vgbM, resolvable; 3' diameter."

ASV Journal Vol 24 No 3 June 1971: "faint in 3-inch 64x, easy in 6-inch 64x."

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.”

On photos taken with the 30-inch Reynolds reflector, 20-inch diaphragm: bright inner part 4.9’ x 3.2’, faint outer regions 8.8’ x 6.6’.

NGC 1466
SL 1, ESO054-SC016
RA 03:44:30

Globular cluster

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, irregularly round, glbM, 30 arcseconds, has a star 7th mag following, and others near." On a second occassion he wrote "Viewed past meridian; found in place; pB, R, gbM, 30 arcseconds."

Shapley and Lindsay ("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) give a diameter of 2.3' and remark "outer stars well resolved." Van den Bergh and Hagen ("UBV photometry of star clusters in the Magellanic Clouds", Astronomical Journal, Vol. 73, 1968) find that the integrated V magnitude through a 60'' diaphragm is 11.6. They classify it as a globular cluster. They find it is an old cluster with B-V = 1.6.

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag globular cluster in the LMC.

h: "pB, mE, vgbM, 90 arcseconds long; pos 125.5 degrees."; "pB, pmE, S, glbM, 25 or 30 arcseconds. (Cloudy)."; "B, mE, pgbM, 90 arcseconds long, 15 arcseconds broad, pos 117.6 degrees."

Hartung notes: “This small nebula is nevertheless conspicuous in a field sprinkled with stars; it is fairly bright and quite narrow, about 2’ x 0.5’ in pa 120 deg, rising in brightness to the central axis.”

ASV Journal Vol 24 No 3 June 1971: "easy, elongated object in 12.5-inch 150x."

A supernova erupted in this galaxy in 1935 (12.5p).
