HCM-6A, was found in 2002 by a team led by Esther Hu from the University of Hawaii, using the Keck II Telescope in Hawaii. HCM-6A is located behind the Abell 370 galactic cluster, near M77 [1] in the constellation Cetus, which enabled the astronomers to use Abell 370 as a gravitational lense to get a clearer image of the object.
