Abstract

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 3 . h 2 photometric and 3 . h 3 spectroscopic periods is also apparent in observations of 1966.
