James Dunlop discovered NGC 1971 (or NGC 1972) = D 93 on 24 Sep 1826 and described "a very faint nebula, about 30" diameter." His position is ~5' SE of the trio NGC 1969/1971/1972. Based on my visual observation I propose that NGC 1971 = D 93, although Steinicke assigns D 93 to NGC 1972. JH independently discovered this cluster (h2875) on 23 Dec 1834 and recorded it as "the 5th of several running together (fig 7, Pl IV); attached to a smaller, No. 4". His position is accurate.

Joseph Turner sketched the field (along with NGC 1958, 1969 and 1972) on 21 Dec 1875 using the 48" Great Melbourne Telescope. See plate III.29 at www.docdb.net/history/texts/1885osngmt________e/index.php#m_3_29

600/800mm - 24" (4/7/08 - Magellan Observatory, Australia): this cluster is the furthest south in a small right triangle of clusters with NGC 1969 1.2' NW and NGC 1972 0.9' NNE. At 260x it appeared bright, fairly small, round, 45" diameter (largest of trio), gradually increases to the center. At 350x, it contains a sharp stellar core or a mag 14 star is superimposed and a star is also on the SE edge. Located 15' SW of a mag 6.1 star (close double) within the southeast side of the LMC's central bar.
