part of the ASAS was V2653Oph. Yet the astrophysical parameters are not obtained for the system.

Observation and data reduction {#sec:observation}
==============================

The 91-cm telescope of the Istituto Nazionale di Astrofisica – Osservatorio Astrofisico di Catania (INAF–OACT) was used to carry out spectroscopy of the target. Details of the telescope and the echelle spectrograph are given by @or. Observations were carried out during eleven nights between 21 June - 05 July 2008. Exposure times were fixed for target star at 2400s.

The reduction of the spectra was done by using the NOAO/IRAF package[^2]. The [*Th-Ar*]{} emission line spectra were used to calibrate the wavelength references of each observations. The S/N ratio of the spectra was at least $\sim$90.

Photometric observations of the system obtained and published in ASAS-3 were used to construct the V-band light curve. For calculation of the orbital phases we tried to improve a better epoch and an orbital period for the system. An orbital period of about 4.394 days was estimated from the photometric observations of the system by the $Hipparcos$ mission. We searched for orbital period using data combined from the [*Hipparcos*]{} and ASAS surveys. Analysis of Variance (AoV) algorithm developed by @AoV89 and implemented
