Abstract: We present accurate differential photometry of two Be stars: NW Ser and V1446 Aql. Both stars show rapid variations in amplitude, probably due to a beating phenomenon. Two additional significant frequencies are also detected in both stars. This would be the first unambiguous ground-based detection of photometric multiperiodicity in Be stars which may constitute a proof of the presence of non-radial pulsations (nrp) as the origin of the short- term variability. Further observations are planned in order to confirm the detected frequencies.
