NGC 5559 is a barred spiral galaxy, located 240 million light-years away in the constellation of Boötes.[1] It was discovered on April 10, 1785, by the astronomer William Herschel.[7]

In 2001, a type Ib supernova was detected within NGC 5559, and was subsequently designated SN 2001co.[8][9] However, in 2003, the supernova was identified as a calcium-rich supernova, as it had strong spectral lines characteristic of calcium.[10] The progenitors of these calcium-rich supernovae are still a mystery.[1]
