Abstract
We have obtained V photometry of the large-amplitude Delta Scuti star CY Aquarii over a 3-week period at observatories in Australia, South A frica and the USA. Analysis of this photometry gives a conservative up per limit of 1.5 mmag for the amplitude of any long-lived secondary os cillation in the star.
