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 VTO=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 1985ApJS...58..561V), we derive the cluster age
to be about 15Gyr.
