PGC 6505 (=
IC 159)

PGC 6626 (= PGC 174178 =
Arp 4)
A 13th-magnitude irregular galaxy (type IAB(rs)m) in Cetus (RA 01 48 25.8, Dec -12 22 53)

Based on a recessional velocity of 1615 km/sec, PGC 6626 is about 75 million light years away, in good agreement with a redshift-independent distance estimate of 65 million light years. Given that and its apparent size of 2.4 by 2.3 arcmin, it is about 55 thousand light years across. The galaxy is one of six chosen by Halton Arp for his Atlas of Peculiar Galaxies as an example of spiral galaxies of low surface brightness, hence its designation as Arp 4.

PGC 6629
A 14th-magnitude spiral galaxy (type Sc?) in
Cetus (RA 01 48 32, Dec -12 23 15)

Based on recessional velocity of 14300 km/sec, about 640 million light years away. Given that and apparent size of 0.6 by 0.4 arcmin, about 100 thousand light years across.
