NGC 124 is a spiral galaxy in the constellation Cetus. It was discovered by Truman Henry Safford on September 23, 1867.[4] The galaxy was described as "very faint, large, diffuse, 2 faint stars to northwest" by John Louis Emil Dreyer, the compiler of the New General Catalogue.[4]
The 17th magnitude supernova SN 2004dd was discovered in this galaxy on 12 July 2004.[5] It was a type II supernova.[6]
