Corwin's Notes
=====
NGC 3048 appears to be a double interacting system in the background of an
undisturbed spiral. An earlier version of SDSS redshifts of the system
suggested that the bright spiral and one of two "in the background" are at the
same distance. However, the latest DR12 version (consulted in July 2015) has
these redshifts:
The brightest southwestern object has z = 0.02956 +- 0.00002
The faintest "middle" object has z = 0.03348 +- 0.00001
The northeastern object has z = 0.03349 +- 0.00001
These confirm the visual impression of an optical alignment.
Marth's single observation has only a position -- given, as usual, to only a
full minute of arc -- and the note "eF". While his observation is probably
dominated by the foreground spiral, I've nevertheless given directional
designations to all three.
