High-speed photometric observations of 10 Aql were obtained during 26 hr over seven nights using a 1-m telescope. A frequency analysis of these observations shows that at least three frequencies are present in the light variations which are tentatively identified as f(1) = 1.4360 mHz, f(2) = 1.3854 mHz and f(3) = 1.2393 mHz, with semiamplitudes (B) of 0.44, 0.33 and 0.28 mmag, respectively. Because the analysis of the light variations suffer from ambiguities due to daily aliasing in the data, further observations will be necessary before a definitive determination of the frequencies can be made.
