PGC 15632 (= PGC 213289)
A 15th-magnitude spiral galaxy (type S?) in Eridanus (RA 04 36 40.3, Dec -02 17 26)
Based on a recessional velocity of 7865 km/sec, PGC 15632 is about 365 million light years away. Given that and its apparent size of 0.2 by 0.2 arcmin, it is about 20 thousand light years across. Near PGC 15637, which see for images.
PGC 15637 (with PGC 213288 = Arp 61)
A 15th-magnitude spiral galaxy (type Sa?) in Eridanus (RA 04 36 40.3, Dec -02 17 26)
Based on a recessional velocity of 9740 km/sec, PGC 15637 is about 450 million light years away. Given that and its apparent size of 1.0 by 0.5 arcmin, it is about 130 thousand light years across.

PGC 213288 (with PGC 15637 = Arp 61)
Listed here because of its association with PGC 15637 as Arp 61
A 15th-magnitude spiral galaxy (type S?) in Eridanus (RA 04 36 39.2, Dec -02 17 09)
(Listed in NED as 2MASX J04363919-0217090.) Apparent size 0.15 by 0.12 arcmin; nothing else known, but if actually interacting with PGC 15637 (which see for images), it would be at the same distance, and about 20 thousand light years across.
PGC 15650
(= ESO 202-041)
A magnitude 14.1 spiral galaxy (type SAB(rs)m) in Pictor (RA 04 36 57.2, Dec -52 10 32)

PGC 15749
(= PGC 435375 = ESO 157-049)
A magnitude 13.5 spiral galaxy (type Scd: sp / E6-7) in Pictor (RA 04 39 36.9, Dec -53 00 46)
Note About Classification: The type is taken from the Spitzer Survey of Stellar Structure in Galaxies. "sp" means the galaxy is a "spindle" (that is, seen edge-on), making it harder to determine the classification (as indicated by the colon after "cd"). "/ E6-7" means that the spiral is enveloped in a faint elliptically-shaped outer envelope, but does not alter the fact that it is a spiral galaxy.
