Abstract
In this article, we have studied the reports of lunar occultations by this project observation’s teams (named APTO) in comparison with other observations of the objects. Thirteen binary stars were selected for this study. All the previous observations of these stars were also collected. Finally, an analysis of O‐C of all reports were performed.
