摘要：

The nearby, metal-rich, halo globular cluster NGC 6366 has been observed in order to obtain its color-magnitude diagram and to search for variable stars. The color-magnitude diagram indicates that the cluster has a reddening E(B-V) of 0.80 (higher than most previous determinations) and a distance of 3.0 kpc. The cluster has numerous blue straggler stars, and a list of 27 candidate blue stragglers is given. However, no blue stragglers are found to be variable, and the implications of this finding are discussed. The one RR Lyrae star in the cluster is studied, and its period and light curve are determined. The structural parameters of the cluster are determined.
