Abstract: We present the analysis of the CoRoT data of the B8IIIe star HD 175869 observed during a short run (27.3 days). The light curve shows low-amplitude variations of the order of 0.3 mmag. A frequency within the range determined for the rotational frequency and its 5 harmonics are detected. Other significant frequencies with a low amplitude of a few ppm are also found. The analysis of line profiles from ground-based spectroscopic data does not show any variation.
