Abstract
The ANTARES detector is an abyssal undersea neutrino telescope in the Mediterranean Sea. The search for point-like neutrino sources is one of the main goals of ANTARES, so a reliable way to evaluate the detector angular resolution and pointing accuracy is needed. In a previous analysis, the deficit in the atmospheric muon flux in the direction of the Moon induced by absorption of cosmic rays was investigated. It has allowed the estimation of the angular resolution and of the pointing accuracy of the detector. In this work the same approach was applied to measure the Sun shadow effect. This analysis is based on the ANTARES data taken in the interval between 2008 - 2015. According to Monte Carlo simulation the expected statistical significance of the analysis is 2.9σ .
