PGC 17109 (=
Arp 52)
A 15th-magnitude spiral galaxy (type S?) in Orion (RA 05 19 40.6, Dec +03 43 47)

Arp 52 consists of the spiral galaxy PGC 17109, and the small companion overlapping its northwest corner (at the upper right of the nucleus in the images below). Based on a recessional velocity of 8375 km/sec, the galaxy is about 390 million light years away. Given that and apparent size of 0.7 by 0.45 arcmin, it is about 80 thousand light years across.
