NGC 5243 with SN2019fck in Canes Venatici
SN2019fck is a type Ia supernova. The SN exploded actually in a companion of NGC5243. This anonymous dwarf galaxy merges currently with NGC5243 which results in tidal streams and tails between the dwarf and NGC5243 as can be clearly seen in the SDSS image. SN2019fck outshines by far the core of the dwarf galaxy.
