  We examine the photometric variability of stars in the M 67 field using
Kepler/K2-Campaign-5 light curves. Variabilities and periods were determined
for 639 stars. The mean photometric period of 28 single Sun-like members stars
in M 67 is 23.4 +/- 1.2 d. This corresponds to a gyro-age of 3.7 +/- 0.3 Gyr,
assuming the periods can be associated with rotation. The intrinsic
variabilities of the solar analogs are greater than the Sun's variability, as
measure from VIRGO fluxes. We also find evidence that the single cluster
members have a different distribution of variability than the binary members.
