Be stars are main-sequence stars and a specific subclass of B type stars with the unique characteristic of showing H I Balmer emission lines in their optical spectra that originates from a circumstellar disk around the star. Over the past 50 years, the Galactic Be star ω CMa has exhibited quasi-regular outbursts, every 8 years or so, when the star brightens by about half a magnitude in the V-band. During these outbursts a new disk is formed during the first 3-4 years, and then dissipates in the following 4-6 years. We have access to a rich dataset (including photometry, polarimetry, interferometry and spectroscopy) of ω CMa since March 1964 covering several outbursts and quiescence phases. Thus, nature has provided us the perfect experiment to study how Be star disks grow and dissipate.
