Abstract

This paper describes the discovery of five new variable stars, AC_V1– AC_V5—two binary systems and three pulsating stars—between 2017 and 2019. They have been included in the AAVSO Variable Star Index, but are being published now. We encourage all observers to further observe these stars so as to better characterize them. It might be interesting to make subsequent observations for constructing O–C diagrams as well as for modeling the binary systems.
