Pulsational mode switching in HD 161796
Description
Photometry of HD 161796 in 1980 shows a low-amplitude (0.08 mag in V) sinusoidal variability of period 43./sup d/ Photometry of the previous year by Percy and Welch shows a variability of similar amplitude but with a 62/sup d/ period, while photometry in 1981 showed the star constant to a level of +- 0.005 mag or less for two months before breaking into oscillation again. Oscillations are neither built up nor damped, but appear at full amplitude immediately before and after cessation
