IC 2150 (= PGC 18000)
Discovered (Jan 31, 1898) by
Lewis Swift (XI-87)
A magnitude 12.8 spiral galaxy (type SB(r)bc) in Columba (RA 05 51 18.5, Dec -38 19 16)
Based on a recessional velocity of 3120 km/sec, IC 2150 is about 145 million light years away, in good agreement with redshift-independent distance estimates of 120 to 165 million light years. Given that and its apparent size of 2.75 by 0.8 arcmin, it is about 115 thousand light years across.

IC 2184 (= PGC 21123)
Discovered (Jan 24, 1900) by
Guillaume Bigourdan (390)
A magnitude 13.1 pair of interacting galaxies in Camelopardalis (RA 07 29 24.9, Dec +72 07 43)
Based on a recessional velocity of 3605 km/sec, IC 2184 is about 165 million light years away. The system was previously classified as an irregular or peculiar spiral galaxy, but is now recognized as a pair of colliding edge-on spiral galaxies, each of probable type SBb pec. The western component is 0.8 by 0.15 arcmin, the eastern is 0.95 by 0.15 arcmin, and the overall size of the region involved in their collision is 1.4 by 1.35 arcmin. Given their probable distance, the individual components are about 45 and 40 thousand light years across, and the system is about 65 thousand light years across. The pair of galaxies should eventually merge into a single larger galaxy, and since we see them as they were in the very distant past, by now they have not only merged, but all the exceptionally bright stars created by their collision have lived out their brilliant but brief lives and blown themselves to bits.

IC 2197 (probably = PGC 213402)
Discovered (May 9, 1888) by
Edward Barnard
A magnitude 16(?) spiral galaxy (type Sm?) in Gemini (RA 07 34 25.3, Dec +31 25 19)
Per Dreyer, IC 2197 (Barnard, 1860 RA 07 25 27, NPD 58 19.5) is "very very faint". (Note: This is one of five nebulae listed by Barnard in A.J. 1897, #422, p. 112.) The position precesses to RA 07 34 23.3, Dec +31 22 37, but there is nothing there. For various reasons Corwin suspects the galaxy above is probably Barnard's object; though he is not certain of the identification, NED and LEDA have adopted his choice (more about this to be posted in the next iteration of this page). Corwin also mentions that Steinicke chose a different galaxy (PGC 1942468) as IC 2197, but doubts it is the correct object. Still, that means there is bound to be confusion about the identification of IC 2197, and Steinicke's choice should also be discussed (as it is, immediately below). Apparent size 0.75 by 0.25 arcmin.
