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

SN 2010el[edit]

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.[7]
