An analysis of data spanning 24 years shows that a secondary 20m periodicity is a persistent feature in photometric observations of TT Ari. This period decreases from 27m in 1961 to 17m in 1985. The 4d beat period of 3h.2 photometric and 3h.3 spectroscopic periods is also apparent in observations of 1966.
