Scientific paper

Photometric observations of the Delta Scuti star EW Aqr (HR 8201 = HD 201707 = BD -15.5908 deg) were made with a 150-cm telescope in Mexico during six nights in September and October, 1982. Analysis of the data produces periods of 0.09664 d, 0.1087 d, and 0.2121 d, with semiamplitudes of 0.013, 0.010, and 0.007 mag, respectively. The ratios of these periods and the light curves for the source suggest that EW AQr is a nonradial pulsator.
