Abstract

A sample of 24 globular clusters was studied photoelectrically for radial variations of the surface UBV colors . For 8 of them, the colors decrease from the centre outwards, by about 0.1 mag in B-V and 0.2 mag in U-B. The colors of the remaining 16 are radially uniform within a few hundredths of a magnitude.
