The Local Volume HI Survey

ESO 318-G013 (HIPASS J1047-38) is a small, edge-on spiral galaxy at a TF distance of 6.5 Mpc. Its nearest neighbour is ESO 376-G016 (HIPASS J1043-37; v_hel = 668 km/s) about 2 degrees away. Our ATCA data show a well-resolved, but somewhat lopsided HI disc extending well beyond the stellar body. While its rotation appears regular, the gas distribution shows some peculiar features. A faint HI tail on the western (receding) side may hint at tidal interactions. We measure F_HI = 9.1 Jy km/s, in agreement with HIPASS (Koribalski et al. 2004), and derive M_HI = 9.1 × 10⁷ M_☉.
