In 2016 it was announced UGC 1382, which was believed to be a passive elliptical galaxy, is actually a giant low surface brightness galaxy (GLSB) which rivals the archetypical GLSB Malin 1 in size. It has two components: a high surface brightness disk galaxy surrounded by an extended low surface brightness (LSB) disk. The main body of the galaxy is embedded in a massive low-density HI disk with a radius of 110 kpc, making this one of the largest isolated disk galaxies known.

600/800mm - 24" (12/21/16): at 282x; fairly faint or moderately bright, fairly small, elongated 4:3 SW-NE, 25"x18", very small bright core, occasional stellar nucleus. Forms a pair (similar distance) with CGCG 386-053 5.5' SW.
