Absolute V-band magnitude (MV) and half-light radius (﹩{r}_{{\rm{h}}}﹩) of MADCASH J074238+652501-dw (large red star) placed in context with other known systems. Black points and triangles are data for MW and M31 dwarf galaxies (e.g., McConnachie 2012), and blue squares are members of the NGC 3109 association, including Antlia and Antlia B (Sand et al. 2015). The small, red, downward-pointing triangle represents DDO 44, another known satellite of NGC 2403 (Karachentsev et al. 1999).
