AM 0605-341 (HIPASS
J0607-34) is a rather compact, barred Magellanic dwarf galaxy at a
membership distance of 7.4 Mpc. Its nearest neighbours are NGC 2188 (HIPASS
J0610-34) and ESO 364-G?029 (HIPASS J0605-33) at projected distances of 35.6
arcmin and 70.2 arcmin. Our ATCA HI maps show a resolved source centred on
the optical galaxy plus extended HI emission on the western (receding) side.
Kirby et al. (2012) model the HI kinematics of the main component and fit a
rising rotation curve. They provide a detailed discussion, including on likely
tidal interactions between AM 0605-341 and its eastern neighbour NGC 2188
which show opposing HI extensions. We measure FHI = 9.3 Jy km/s,
in agreement with HIPASS (Koribalski et al. 2004), and derive MHI
= 1.2 × 108 M☉.
