ESO 379-G024 (HIPASS
J1204-35) is a dwarf irregular galaxy at a Hubble distance of 4.9 Mpc,
also located in the outskirts of the Cen A group. Using HIPASS we measure
vsys = 631 km/s and obtain vLG = 356 km/s. The 6dF
optical velocity for ESO 379-G024 is 652 ± 55 km/s. Its nearest neighbour
is likely the galaxy ESO 379-G007 (HIPASS J1154-33), ~3 degrees away. The ATCA
HI distribution of ESO 379-G024 is noticeably lopsided, with more HI gas
on the south-western side. The HI velocity field is somewhat irregular,
suggesting a mixture of low rotation and peculiar velocities. We measure
FHI = 2.6 Jy km/s, within the uncertainties of the HIPASS
FHI, and derive MHI = 1.5 × 107
M☉.
