This galaxy pair really is one of the most poorly known objects in the sky.......
I just interrogated the 6dF redshift survey, which was supposed to provide recession velocities for nearly all of the most obvious galaxies in the southern sky; yet it seems that one of these two fairly prominent galaxies does not have a redshift, even in this massive database!
Therefore.....I am unable to confirm the large velocity difference of about 3400 km/s that was reported in some older data.
It does seem that the spiral member of the pair is very distant, at 7622 km/s redshift (in the heliocentric frame).
However, as far as I am concerned, the question of whether this is an apparent pair or whether it is a physical pair, is not yet resolved at 100% certainty. Perhaps I should write to Prof Tony Fairall in South Africa....he knows most everything about southern redshifts.
