Abstract
We report the discovery of an unusual low-ionization broad absorption line quasar at z = 1.776 which exhibits absorption lines from many excited states of Fe II. This member of the rare class of "FeLoBAL" quasars was serendipitously found in a mid-infrared (MIR) survey of distant clusters carried out with the ISOCAM camera. ISO J005645.1-273816 has a high MIR to UV luminosity ratio, suggesting a strong dust obscuration plus emission from very hot dust. This characteristic makes MIR surveys particularly efficient at detecting LoBAL quasars.
