The bright Be star HR 9070 is photometrically variable with a range of about 0m.03 and a period of about 0d.307. The period appears to be stable to better than 1% over many years. The light curve is sinusoidal. There are no significant variations in uvby colors. Of all possible explanations for the variability, the most likely is nonradial pulsation.
