Recent observations of zeta Tau
We report a recent decrease of the Ha emission strength in a bright Be shell star zeta Tau. The decrease of emission is caused presumably by depletion of the material in the circumstellar disc which resulted in disappearance of pronounced long term radial velocity and V/R variations. The period analysis of the equivalent width data gives the period of 132 days for the Ha equivalent width and about 70 days for the He I 6678 A line.
