Description:
    We present for the globular cluster NGC 5927 the first multicolor CCD
    photometry that reaches below the cluster's main sequence turnoff. The
    turnoff is located approximately at V_TO_=20.1mag, (B-V)_TO_=1.18mag,
    (V-I)_TO_=1.30mag. There is a hint of horizontal branch morphology
    variations with distance from the cluster center. Using the isochrones
    of VandenBerg & Bell (1985ApJS...58..561V), we derive the cluster age
    to be about 15Gyr.
