The long-term behaviour of the photometric variability of Beta Cassiopeiae J/A+AS/108/55 J/A+AS/108/55 Beta Cas The long-term behaviour of the photometric variability of Beta Cassiopeiae E Riboni E Poretti G Galli Astron. Astrophys. Suppl. Ser. 108 55 1994 1994A&AS..108...55R delta Scuti methods: data analysis stars: individual (Beta Cas) stars: oscillations 1003 V measurements of {beta} Cas divided into three observing seasons are discussed. Their analysis performed with both the Vanicek least-squares and the classical O-C methods led us to the confirmation of the monoperiodic pulsation. All the photometry available on {beta} Cas (spanning 25 years) was also analyzed; the amplitude of the light curve was found to be constant, while a small period variability can be inferred.
