NGC 1311

NGC 1311 (HIPASS J0320-52) is a Magellanic barred spiral galaxy at a TRGB distance of 5.22 Mpc (Tully et al. 2013). Its closest neighbours are IC 1959 (HIPASS J0333-50) and ESO 154-G023 (HIPASS J0256-54) and ESO 199-G007 (HIPASS J0258-49), all separated by ≳1 Mpc. Eskridge et al. (2008) conduct a detailed study of ultraviolet, optical and near-infrared HST images of NGC 1311 revealing 13 candidate star clusters. NGC 1311 and IC 1959, both low-luminosity star-forming galaxies, are located in the foreground to the galaxy group LGG 93 (Pisano et al. 2011). Our ATCA HI maps show a box-shaped HI distribution, somewhat truncated on the north-eastern side where faint stellar emission is prominent. The fat inner disc suggests the presence of extra-planar HI gas; some deviations of the velocity field are observed to the north-eastern side. We measure FHI = 13.6 Jy km/s, in agreement with HIPASS (Koribalski et al. 2004), and derive MHI = 8.7 × 107 M.
