We have obtained complete light curves from the photometry obtained by [*Hipparcos*]{} [@Perryman+97aa] and All Sky Automated Survey, ASAS, [@Poj02]. We have also obtained an extensive spectroscopy using the FRESCO [é]{}chelle spectrograph at the telescope of Catania Astrophysical Observatory.

[@och] measured the visual magnitude of 8.90 mag with a precision of one tenth of a magnitude and a color of G5 using “microfiche” photographic observations for V2653Oph. The eclipsing character of V2653Oph (HD162811;BD+03$^{o}$3514; HIP87511; V=9.49, B-V=0.60 mag) [^1] was discovered by the $Hipparcos$ satellite mission, the primary eclipse having an amplitude of 0.09mag. The depth of the secondary minimum is nearly equal to that of the primary one. The first eclipse light curve was roughly revealed by the $Hipparcos$ observations. @Kaz99 designated it as V2653Oph in the [74th Name-list of Variable Stars]{}, and classified it as an eclipsing binary. In recent years, large-scale photometric surveys, such as All Sky Automated Survey (ASAS) [@pojmanski], $MOST$[@wal], $CoRot$[@bag], $Kepler$ [@gil],etc. have been conducted with the main aim of looking for transiting exoplanets. The valuable by-product of this search has been the very large number of well sampled eclipsing binary light curves. One of the eclipsing binaries observed at the Las Campanas Observatory as
