NGC 5559 is a barred spiral galaxy, located 240 million light-years away in the constellation of Boötes. It was discovered on April 10, 1785, by the astronomer William Herschel.
In 2001, a type Ib supernova was detected within NGC 5559, and was subsequently designated SN 2001co. However, in 2003, the supernova was identified as a calcium-rich supernova, as it had strong spectral lines characteristic of calcium. The progenitors of these calcium-rich supernovae are still a mystery.
