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

History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 1936 = IC 2127, which see, is another of the HII regions in this part of the LMC found by JH. He has it in six different sweeps, and his position is very good.

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]

He observed it from Paramatta, New South Wales, and included it as No. 175 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a pretty large rather faint nebula, about 5' diameter, irregular figure, partly resolvable into stars of mixt magnitudes. The nebulous matter has several seats of attraction, or rather it is a cluster of small nebulae with strong nebulosity common to all."

John Herschel

John Herschel recorded it as "pretty bright, small, round. Another chief nucleus or knot of the cluster nebula." He next recorded it as "pretty bright, small, round, The fourth of a group of four, connected by stars, etc." He next called it "the third nebula in a group of 3." The next observation saw it as "the last of three nebulae in a zig-zag formed cluster." The final observation saw it as "the southern and brightest nebular nucleus of a great branching cluster." The compound nebula has components NGC 1929, 1934, 1935 and NGC 1936.

Shapley & Lindsay

("A Catalogue of Clusters in the Large Magellanic Cloud", Irish Astronomical Journal, Vol. 6, 1963) give the grouping dimensions of 4.5' x 1.7' and remark "bright loose stars in dense nebulosity."
