(Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,BM,DIFKNY SSTR BARSUSP.
Shobbrook (1966, Mon. Not. R. astr. Soc., Vol 131, p351-363) notes that this member of the Grus Cluster has V = 11.81, B-V = 0.58 and U-B = 0.05. It measures 3.2 by 2.8.
Steve Coe, observing with a 13" f/5.6, notes: "Pretty faint, pretty large, little brighter in the middle and little elongated (1.5 X 1) in PA 90 at 100X. There is a companion to the west, NGC 7214A, it is very, very faint, small and round and only seen occaisonally, in moments of good seeing."
