The Local Volume HI Survey (LVHIS)

UGCA 442

UGCA 442 (HIPASS J2343-31) is a Magellanic barred spiral galaxy oriented close to edge-on. Karachentsev et al. (2003) give a TRGB distance of 4.27 ± 0.52 Mpc. Its nearest neighbour is the bright spiral galaxy NGC 7793, just over 3 degr away Using our ATCA HI data we find an extended, regular rotating HI disc apart from minor deviations towards the southern (receding) end (see also Cote et al. 2000). We measure FHI = 52.2 Jy km/s, in agreement with HIPASS (Koribalski et al. 2004), and derive MHI = 2.2 × 108 M. Hα imaging of UGCA 442 revealed five HII regions within the stellar disc, which are discussed by Miller (1996), Lee et al. (2003), and Meurer et al. (2006).
