Abstract
1003 V measurements of beta Cas divided into three observing seasons a re discussed. Their analysis performed with both the Vanicek least-squ ares and the classical O-C methods led us to the confirmation of the m onoperiodic pulsation. All the photometry available on beta Cas (spann ing 25 years) was also analyzed; the amplitude of the light curve was found to be constant, while a small period variability can be inferred .
