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

Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vF, R, outlying." He wrote of it as the second of an irregular string of nebulae and stars.

West to east there are NGC 220, NGC 222, and NGC 231.

Published comments

Lindsay, E.M

Lindsay, E. M. "Note on NGC and IC objects in the Small Magellanic Cloud" IAJ, Vol 6. p 2-3. From 30-minute 103a-O ADH plates: "Position should be 4'N of NGC position, lying between NGC 220 and 231."

Kron (1956)

Kron, G. E. (1956) Star Clusters in the Small Magellanic Cloud: I. Identification of 69 Clusters. PASP, Vol. 68. [1956PASP...68..125K]

Describes it as a blue cluster, noting the presence of bright blue giant stars. He notes that it is concentrated towards the centre, has a star nearby and exhibits emission nebulosity. Lindsay ("Clusters in the Small Magellanic Cloud", Irish Astronomical Journal, Vol. 4, 1956) classifies it as an open cluster.

Sulentic & Tifft (1973)

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