NGC 1566, commonly known as the Spanish Dancer [3][4] is an intermediate spiral galaxy in the constellation Dorado. It is the dominant[5] member of the Dorado Group and also its brightest member.[6][7] It is one of the brightest Seyfert galaxies in the sky.[5] Its absolute luminosity is 3.7×1010 L☉.[8] It contains 1.4×1010 M☉ of H I.[8]

SN 2010el

On June 19, 2010, Berto Monard from South Africa detected a magnitude 16 supernova 13" west and 22" south of the center of NGC 1566 at coordinates 04 19 58.83 -54 56 38.5.[9]
