On April 16, 2010 UT, the Palomar Transient Factory automated wide-field survey detected a supernova on the outskirts of NGC 5177. [3] The supernova is known as SN 2010cr [4] and is located at 13:29:25.11 +11:47:46.4. [3] 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. [3] The Hubble Space Telescope took STIS/UV spectroscopic observations on May 3, 2010. [5]
