摘要：
Simultaneous uvby Stromgren photometric observations of the comet Hale-Bopp have been collected during nearly three weeks. The Fourier transform method has been used to analyse the periodicities in luminosity present in this comet. Two different periodicities have been found: a long period of 7.19 days and a shorter one of 5.5 hours. The 5.5-hour periodicity may correspond to a full rotation of 11 hours whereas the 7.19-day periodicity could be related with the precession period. Other possibilities are discussed.
