AbstractWe present a series of optical spectroscopic and near-infrared photometric observations of the Be star X Persei, from the beginning of the recent emission phase. Our data show that after the latest extended low state (ELS), both the equivalent width (EW) of the H alpha emission line and the JHK luminosities gradually increased. The recent maximum H alpha EW and JHK magnitudes are more than but comparable to the 1986-1989 maxima, which reflects a more extensive and denser envelope in the new emission phase.
