BV photometry of quadrupole system ET Bootis

► We present Johnson BV observations and analysis of quadrupole system ET Bootis. ► The system contains an eclipsing (EB) and a non-eclipsing (NEB) binary system. ► Photometric analysis of ET Bootis was performed with WD code. ► Previous orbital solution of the EB enabled us to reveal physical properties. ► Photometric solution leads us to the color and magnitudes of the components in EB. ► Moreover, we determined general photometric properties of the NEB.
