## Abstract Spectroscopic and photometric observations of the variable ET And were carried out in the years 1981/82. In addition to the known periodical variation of the radial velocities of 48.308 days produced by a companion and the photometric period of 1.61883 days probaly resulting from the ro

New spectroscopic and photometric observations of the variable Ap star ET And carried out 1982 and 1983 confirm once again the existence of short-time variations. Iior the radial velocity variations a period of 0.19771 days and for the light variations a period of 0.0989 days was found. Some spectro
