  We present the results of a study of the stellar activity in the solar
neighborhood using complete kinematics (galactocentric velocities U,V,W) and
the chromospheric activity index $\log R'_{\rm{HK}}$. We analyzed the average
activity level near the centers of known moving groups using a sample of 2529
stars and found that the stars near these associations tend to be more active
than field stars. This supports the hypothesis that these structures, or at
least a significant part of them, are composed of kinematically bound, young
stars. We confirmed our results by using Galaxy Evolution Explorer (GALEX) UV
data and kinematics taken from the Geneva-Copenhagen Survey for the stars in
the sample. Finally, we present a compiled catalog with kinematics and
activities for 2529 stars and a list of potential moving group members selected
based on their stellar activity level.
