NGC 1187

NGC 1187 is a spiral galaxy located about 60 million light-years away in the constellation of Eridanus. NGC 1187 has hosted two supernova explosions since the 1980s. In October 1982, the first supernova seen in NGC 1187 — SN 1982R was discovered at La Silla Observatory[1] and, in 2007, the amateur astronomer Berto Monard in South Africa spotted another supernova in this galaxy — SN 2007Y.[3]
