The Local Volume HI Survey

HIPASS J1351-47 is a dwarf irregular galaxy at α,δ(J2000) = 13:51:21.2, -46:59:53.0 as measured using our ATCA HI data. It was discovered by Banks et al. (1999) who measured v_sys = 530 km/s. Its TRGB distance of = 5.73 ± 0.73 Mpc (Karachentsev et al. 2007) is similar to that of HIPASS J1348-37; both are located in the outskirts of the Cen A Group. Its nearest neighbours appear to be several dSph galaxies, for example LEDA 166179. The low Local Group velocity (v_LG = 291 km/s) of HIPASS J1351-47 indicates an infall velocity of ~140 km/s towards the group. Our ATCA HI data show a marginally resolved source and hint at a kinematic PA of ~45 degr. We measure F_HI = 3.6 Jy km/s, in agreement with HIPASS (Meyer et al. 2004), and derive an HI mass of 2.8 × 10⁷ M_☉.
