AO Cam and AM Leo are two short-period overcontact binary systems whose physical properties are nearly the same. In the present paper, three CCD times of minimum light for AO Cam and two photoelectric eclipse times for AM Leo are presented. Combining the new determined eclipse times with others comp...
