[Pair with IC 4837]
Oct 1/2, 1978
103ao + GG385
The pair has an angular separation of 3.4'.
Only IC 4837 (the late-type Sc) is in the
Shapley-Ames, although IC 4839 (the more regular Sab)
is nearly as bright. No redshift is known for
IC 4839 (c. 1990). The redshift for IC 4837 is
v_o = 2575 km/s, as listed in the RSA2. If IC 4839
is at the same redshift distance of 52 Mpc, the
projected linear separation of the pair is 55 kpc.
The spiral morphology of IC 4837 (shown
alone at the right) is too normal to provide
evidence of tidal interaction. The extension of the
outer arm on one side of the pattern, although
asymmetric, is not unusual even in isolated
Overexposed center, bright knotty arms, very faint (R): 2.4 x 1.9.

Did (Sandage, A.R. 1978, A.J., 83, 904) obtain the redshift of this,
rather than that of the nearby IC 4837, as listed in his catalog?
