Abstract:
We discuss the methodology and some preliminary results of a survey of
the chromspheric Ca II H & K line strengths in a sample of solar-type
stars in the galactic open cluster M67. We compare the distribution of
H & K line strength among the solar counterparts in this cluster with that
seen in the contemporary Sun during the course of its 11-year cycle.
