Using the UPSO 1-m Sampurnanand reflector telescope equipped with a fast photometer, we observed the chemically peculiar (CP) star HD 98851 for a total of around 30 hours on 5 different nights between January to April 2000. From the Fourier analysis of our data we have found that HD 98851 pulsates with periods of 75.76 min and 151.52 min and amplitudes ? 25 mmag and 12 mmag respectively. The star appears to be a ? Scuti variable.
