ESO 308-G022 (HIPASS
J0639-40) is a rather isolated dwarf irregular galaxy at a Hubble
distance of 7.7 Mpc. Optical and infrared H-band imaging by Parodi et al.
(2002) and Kirby et al. (2008), respectively, reveal its stellar structure.
Our ATCA HI maps show a resolved, regularly rotating HI disc. We measure
FHI = 4.4 Jy km/s, in agreement with HIPASS (Meyer et al. 2004),
and derive an HI mass of 6.1 × 107 M☉. A
kinematic analysis of the LVHIS data by Kirby et al. (2012) results in a
rising rotating curve with vmax = 40 km/s at a radius of 100 arcsec
(4.1 kpc).
