Note About Classification: The type is taken from the Spitzer Survey of Stellar Structure in Galaxies. "sp" means that the galaxy is a "spindle" (that is, seen "edge-on"), making it harder than usual to determine the classification.
Above, a 12 arcmin wide DSS image centered on spiral galaxy PGC 11139 PGC 11491 (with PGC 11493 = Arp 108)
A 15th-magnitude lenticular galaxy (type S0/a?) in Eridanus (RA 03 03 05.5, Dec -22 13 02)
Apparent size about 0.9 by 0.5 arcmin. Used in the Arp Atlas as an example of an elliptical galaxy connected to a spiral galaxy (PGC 11493).

A 15th-magnitude spiral galaxy (type Sbc? pec) in Eridanus (RA 03 03 07.2, Dec -22 12 20)
Apparent size about 0.9 by 0.5 arcmin. Used in the Arp Atlas as an example of an elliptical galaxy (PGC 11491, which see for images) connected to a spiral galaxy.
