g′ + r′ color image showing FDS11_LSB1, FDS11_LSB2 and FCC252. Colors are displayed for the areas brighter than μ_r′> 26 mag arcsec^-2. Only r′-band image is shown for the levels fainter than that. FDS11_LSB1 and FDS11_LSB2 are separated by projected distance of 15 kpc from each other and ~7 kpc from FCC252, which is a dwarf elliptical galaxy spectroscopically confirmed to be in Fornax (radial velocity = 1415 km s^-1, Drinkwater et al. 2001b). The morphology of these large UDGs is very elongated and may be due to tidal interactions.
