Scientific paper

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 (1985), we derive the cluster age to be about 15Gyr.
