New Spectroscopic Redshift Places PEARLSDG in a Group at ∼124 Mpc

PEARLSDG was previously reported as an isolated dwarf galaxy with a TRGB distance of 30 Mpc. New data show this to not be the case. We report a new spectroscopic redshift of 0.02809, which argues for an association with a group of galaxies at ∼124 Mpc.
