PGC Objects 24500 - 24999

PGC 24836 (= Arp 7)
A 13th-magnitude barred spiral galaxy (type SB(rs)bc) in Hydra (RA 08 50 20, Dec -16 34 46)

Based on recessional velocity of 5505 km/sec, about 250 million light years away. (NED also lists a redshift-independent distance estimate of 19 million light years, which must refer to a different object, as it would make the galaxy impossibly small.) Given that and apparent size of 1.3 by 1.0 arcmin, about 90 thousand light years across.

A 17th-(B)magnitude galaxy (type S?) in Lynx (RA 08 53 06, Dec +33 22 43)

Based on recessional velocity of 25845 km/sec, about 1150 million light years away. Given that and its apparent size of 0.35 by 0.3 arcmin, about 120 thousand light years across
