DESI Legacy image cutout of the compact dwarf galaxy PGC 3080368, the S2 intruder galaxy in Wong et al. (2006). This deep image reveals an outer shell on its south-west side, also detected in the amateur data shown in Fig. 1 (top panel). The blue smaller galaxy to the south of S2 is possibly a background distant galaxy. The field of view is about 4×4 arcmin. North is up and east is left.
