A small anomalous galaxy of NGC520 has been positioned near a boundary between Pisces and Cetus. The galaxy has a visual size of about 4 arc minutes and 12th magnitude in brightness. Although one of minor deep sky objects, we can detect its warped figure occurred by an inter-galactic collision. This galactic colliding pair is fairly easy to observe through amateur equipments same as famous pair of "The Antennae" in Corvus. NGC520 has a nickname of "The Flying Ghost", floating about 100 millions light years away and has a real size of about 100 thousands light years.
