NGC 5112 is a barred spiral galaxy in the constellation Canes Venatici. It was discovered on 17 March 1787 by German-British astronomer William Herschel.[3] This galaxy is in close physical proximity to the edge-on dwarf spiral NGC 5107.
On 4 March 2015, a supernova candidate was discovered in NGC 5112, and designated PSN J13215756+3843229. Spectral analysis suggested that it was instead a supernova imposter, possibly an outburst from a luminous blue variable.[4]
