The Local Volume HI Survey

HIPASS J1441-62 is a dwarf irregular galaxy at α,δ(J2000) = 14:41:42.2, -62:46:04.2 as measured from our ATCA HI data. The galaxy is located at low Galactic latitude (l,b = 315.2 degr, -2.55 degr, A_B = 4.9). Its systemic velocity of v_hel = 672 ± 8 km/s (Koribalski et al. 2004) and v_LG = 461 km/s suggest an approximate Hubble distance of 6.0 Mpc. No stellar counterpart is identified. Its nearest known neighbour is the Circinus galaxy, ~4 degr away. Our ATCA data show a resolved HI distribution and a regular velocity field (PA ~ 260 degr). We measure F_HI = 2.4 Jy km/s, within the uncertainty of the HIPASS F_HI (Koribalski et al. 2004), and derive M_HI = 2.0 × 10⁷ M_☉.
