NGC 3344 is a relatively isolated[8] barred spiral galaxy in the constellation of Leo Minor.[9] It was discovered by German-British astronomer William Herschel on 6 April 1785.[10] This galaxy is located at a distance of 22.5 million light-years (6.9 Mpc)[4] from the Milky Way. It has an apparent visual magnitude of 9.7 and spans an angular size of 7.1′ × 6.5′.[2] The nearest bright galaxy is NGC 3274 at a projected separation of 3.7°.[8] NGC 3344 belongs to the galaxy group known as the Leo spur, which is a branch of the Virgo Supercluster.[11]

The morphological classification of NGC 3344 is (R)SAB(r)bc,[6] which indicates it is a barred spiral galaxy (SAB) that exhibits rings (R, r) and moderate to loosely wound spiral arms (bc).[12] The plane of the galaxy is inclined at an angle of around 25.5° with the long angle of the resulting elliptical shape aligned along a position angle of −23.9°.[8] There is both an inner ring and outer pseudo-ring, with the prominent arms radiating outward from the inner ring and the relatively small and slightly elliptical bar being situated inside. At the center of the bar is an H II nucleus with an angular diameter of about 3″.[8]

Supernova

[edit]

One supernova has been observed in NGC 3344: SN 2012fh, a Type Ib/Ic that peaked at magnitude 15.1. It was discovered by Masaki Tsuboi on 18 October 2012.[13][14][15]
