Abstract

The CLUE experiment, located in La Palma island at 2200 m a.s.l.. is an array of 3x3 telescope, detecting the UV (190-230 nm) Cerenkov light produced by atmospheric showers. Due to the higher atmospheric absorption in the UV range than in the visible one, CLUE cannot apply existing algorithms normally used in IACT experiments to determine primary cosmic ray direction. In this paper we present a new method developed by CLUE. The algorithm performances were evaluated using simulated showers. CLUE experiment collected data in the last, two years pointing to AGN sources and to Moon. The preliminary results obtained using the new technique on Crab Nebula and on Markarian 421 were presented in a previous paper. Here, we present the preliminary observation of Moon Shadow employing the new method. As described in the paper, we expect in a near future. improvements on AGN sources and on Moon Shadow measurement.
