NGC 5177 is a galaxy. Based on a redshift of 6467 km/s the galaxy is crudely estimated to be about 300 million light-years away.[1]
Supernova
On April 16, 2010 UT, the Palomar Transient Factory automated wide-field survey detected a Supernova on the outskirts of NGC 5177.[2] The supernova is known as SN 2010cr[3] and is located at 13:29:25.11 +11:47:46.4.[2] A confirmation spectrum was taken with the Palomar Hale telescope on April 17 UT which showed it to be approximately 13 days before peak brightness.[2] The Hubble Space Telescope took STIS/UV spectroscopic observations on May 3, 2010.[4]
