## Abstract We present results from the spectroscopic followโ€up observation of additional QSO candidates in the variability and proper motion (VPM) survey field around M92. In the previous studies, the VPMsurvey has shown to be an efficient way to select QSOs; the QSO sample was confined to the mag
