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

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 object from Paramatta, New South Wales, and included it as No. 547 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a small faint round nebula about 15 arcseconds in diameter."

John Herschel

John Herschel recorded it as "pB, S, R, psbM." On a second occassion he called it "pB, pL, 1' diameter; a miniature of the last neb. of this sweep."

Published comments

pB, pS, lE 80deg, rather similar to 1316."

Helwan Obs. Bulletin No 21 (1920)

pB, pS, R, vB central part lE 60deg, and outer nebuloisity with sharply defined edge - possibly open spiral. There is only one nebula in this position. Description in HOB 9 cancelled. See also HOB 15.

de Vaucouleurs, G. (1956)

"Survey of bright galaxies south of -35° declination", Mem. Mount Stromlo, No. 13. On photos taken with the 30-inch Reynolds reflector, 20-inch diaphragm: bright inner part 1.4' x 1.4', faint outer regions 2.3' x 2.2'. Remarks: vSBN: 0.6' x 0.5', very faint bar

Sandage, A. (1975)

(Astrophysical Journal, 202, 563-582) notes that this galaxy is a member of the Fornax Cluster. Members include NGC 1316, NGC 1317, NGC 1326 & NGC 1399.

NGC 1317 = NGC 1318

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads E,R,BM,DIFHALO,SO).

Modern observations

AJ Crayon

AJ Crayon, using an 8" f/6 Newtonian, notes: "is barred spiral galaxy. At 100x it is 3'x2' 12m, in northeasterly position angle, with NGC 1316 5' south and no other galaxies in field."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, little elongated 1.2 X 1 in PA 0, pretty suddenly brighter middle at 135X."
