Description
Preliminary results on new CCD photometry inV andB bands of
approximately 5000 stars in four overlapping fields in the globular
cluster M3 are presented. The colour-magnitude diagram shows a very
well-defined sequence with a small scatter, going fainter than
previously published work on this cluster. The turn-off point found
atV=19.1±0.2 mag and (B-V)=0.445±0.01, is slightly redder
than those obtained in previous studies.
