SDSS J090152.05+624342.6: A New "Overlapping-Trough" FeLoBAL Quasar At Z$\sim 2$

We here report an identification of SDSS J090152.04+624342.6 as a new “overlapping-trough” iron low-ionization broad absorption line quasar at redshift of $z\sim 2.1$. No strong variation of the broad absorption lines can be revealed through the two spectra taken by the Sloan Digital Sky Survey with a time interval of $\sim 6$yr. Further optical and infrared spectroscopic study on this object is suggested.
