Abstract

This paper describes a joint campaign carried out by Instituto Copérnico and Observatorio Cristo Rey, both in Argentina, in a typical professional-amateur relationship. The target object was the bright d Scuti star V393 Carinae, lying close to the open cluster NGC 2516 in the southern Milky Way.

We performed several CCD observing runs during different nights. The complete set of observations appears to show slight variations in the mean period and phase shift, compared to previous observations.
