SN 2005cs was a supernova in the spiral galaxy M51,[3] known as the Whirlpool Galaxy. It was a type II-P core-collapse supernova, discovered June 28, 2005 by Wolfgang Kloehr, a German amateur astronomer.[5] The event was positioned at an offset of 15 west and 78″ south of the galactic nucleus of M51.[2] Based on the data, the explosion was inferred to occur 2.8 days before discovery.[6] It was considered under-luminous for a supernova of its type, releasing an estimated 3×1050 erg in energy.[4]

The progenitor star was identified from a Hubble Space Telescope image taken January 20–21, 2005. It was a red supergiant with a spectral type in the mid-K to late-M type range and an estimated initial (ZAMS) mass of 9+3
−2
 M
. A higher mass star enshrouded in a cocoon of dust has been ruled out.[7]
