2001A&A...378L..33A

We report that the intermediate amplitude δ Scuti star V1162 Ori has changed its main pulsational period in the course of the year 2000. This new period change falls in a sequence of period changes observed during the last 5 years. While the average amplitude value of all our new data, 63mmag, fits a cyclic amplitude variation suggested by Arentoft et al. (2001A&A...374.1056A), splitting the data up in smaller subsets discloses significant deviations from regularity, with stretches of constant amplitude during short intervals of time. The new data show that the amplitude of one of the secondary frequencies, f₂, has in 3 years dropped from more than 3mmag to now about 1mmag, and that the previously obtained f₅ probably is a 1d^–1 alias of the real frequency. We present the newly acquired times of minimum and maximum light as support for subsequent observing campaigns.
