ESO 294-G010
is a dwarf galaxy at a TRGB distance of 1.92 ± 0.10 Mpc (Karachentsev et
al. 2002). It is a member of the NGC 55 /
NGC 300 subgroup in Sculptor. Optical images
show a rather smooth stellar body typical of dwarf spheroidal galaxies, whereas
GALEX UV images clearly reveal a clumpy inner structure. Some signs
of star formation are present (Jerjen et al. 1998, Karachentsev et al. 2002).
ATCA HI data show a weak source around ~106 km/s, slightly offset from its
optical position as already indicated by Bouchard et al. (2005). It remains
unclear if the detected HI emission belongs to the dwarf galaxy. The optical
velocity of 117 ± 5 km/s (Jerjen et al. 1998) is also slightly offset.
We measure FHI = 0.1 Jy km/s and derive MHI = 9 ×
104 M☉. ESO 294-G010 appears to be similar to dwarf
galaxies of mixed type like Phoenix, LGS 3 and KK 3.
