摘要：

We present first results of an ongoing study of BAL QSO variability. Our goal is to infer the amplitude and the timescale of absorption-line variations. While about 75% of our BAL QSOs show no or only minor variations, we discovered the transition of a weak BAL QSO into a strong Lo-BAL QSO, with the MgII lambda 2798 emission line and the adjacent FeII UV emission completely vanishing in less than 10 years.
