Photometric and spectroscopic observations of the neglected near-contact binary Cl* Melotte 111 AV 1224

This paper presents a photometric and spectroscopic study of the short-period binary star Cl*~Melotte~111~AV~1224. Measurements in the B, V, and R passbands obtained during three observing runs between 2014 and 2017 and medium-resolution spectra secured in 2014, are analyzed together with public data from the SuperWASP and LAMOST projects.
