First amateur spectroscopic observations of non-radial pulsations of zeta Oph are published in IBVS 6034. HeI 6678 equivalent width measurements (spectral resolution R = 14000) in May 2012 spectra have been used for investigation of periodicities. Period and phase analysis leads clear to a period of 0.643 d.
