Abstrakt: Spectroscopic observations of the broad-absorption-line QSO (BAL QSO) H1011+091, an object with a rich and complex emission/absorption-line spectrum are presented. Consideration is given the recent suggestions that this object possesses two sets of emission lines and an attempt is made to show that an alternative interpretation is more consistent with the data. Specifically, the apparent doubling of the lines may be due to a combination of low-velocity broad-absorption-line material and unusually strong Al III lambda 1858 emission.
