摘要：

As a part of our continuing program, we have obtained CCD color-magnitude diagrams for the bright globular cluster NGC 2808 in the four colors comprising BVRI. From a comparison of four different CMDs with theoretical isochrones, we arrive at an age of 16 ± 2 Gyr, assuming a value for [Fe/H] near - 1.3.
