The Local Volume HI Survey

AM 1321-304 (HIPASS J1324-30) is a Magellanic dwarf irregular (dIm) galaxy at a TRGB distance of 4.63 Mpc (Karachentsev et al. 2002). Its nearest large neighbour is the spiral galaxy M 83 at a projected distance of 173.7 arcmin. Our ATCA HI maps reveal a marginally resolved source without a distinct velocity gradient. We measure F_HI = 1.7 Jy km/s, in agreement with Begum et al. (2008) who observed AM 1321-304 as part of the FIGGS project. The HIPASS F_HI of 3.9 ± 2.5 Jy km/s is higher but with a large uncertainty (Banks et al. 1999). Begum et al. (2008) measure an HI diameter of 1.4 arcmin (approx. the optical diameter).
