We investigate the short-term photometric variability detected in the Be star Theta CrB, analyzing 235 measures in Stromgren y filter distributed over 10 nights. The power spectrum analysis of the light curve points out a long-term trend to which a short-time variation is superimposed. Both the 1.15 and 2.18 c/d frequencies represent satisfactorily these rapid changes. The 2.18 c/d option coincides with the frequency revealed by Hubert et al. (1991) in the profile variations of the HeI 4471 and MgII 4481 lines during almost the same observational period.
