IC 337 is presumably a bar-spiral galaxy of the Hubble type SBm in the constellation Eridanus in the southern sky . It is estimated to be 136 million light years from the Milky Way . At the position given by Lewis Swift (RA 03 37 03.9, Dec-06 43 19) there is no object. PGC 13308, a low brightness galaxy just over a minute to the west, appears to be a possible candidate since Swift's declinations were more accurate than his proper ascents. The entry may refer to the galaxy PGC 145722 . However, there are also inconsistencies regarding the description.
The object was discovered by Lewis A. Swift on December 25, 1889 .
