We report on the discovery of broad Balmer absorption lines variability in the QSO SDSS J125942.80+121312.6, based on the optical and near-infrared spectra taken from the SDSS-I, SDSS-III Baryon Oscillation Spectroscopic Survey (BOSS), and TripleSpec observations over a timescale of 5.8 years in the QSO's rest-frame. The blueshifted absorption profile of H$\beta$ shows a variation of more than 5$\sigma$ at a high velocity portion ($>3000\ \mathrm{km\ s}^{-1}$) of the trough. We perform a… Expand
