NGC 3239 is an irregular galaxy in the constellation of Leo. [2] It was the host of SN 2012A, the first supernova discovered in 2012 and a Type II-P that reached a peak visual magnitude of +13.83. [3] [4] The galaxy was discovered in 1784 by William Herschel [5] and is part of the New General Catalogue. It harbors a large and relatively bright H II region in its southeastern section that was first cataloged by Russian astronomer Boris Vorontsov-Velyaminov as VV95b. [6] It's believed that NGC 3239 is the result of a galactic merger with a low-mass galaxy. [7]
