Abstract A trend of decreasing Hα emission over a period of thirty minutes is apparent in a series of spectra of X Persei taken on 31 December, 1987. This change appears to be astrophysical in origin and it indicates an anomalous state for X Persei that may be linked to its transition from a Be star to a normal B star, which occurred sometime between March 1988 and November 1990.
