The ARGO-YBJ experiment, under construction at the Yangbaijing Laboratory (P.R. China, 4300 m a.s.l.), is a full coverage detector of dimension 7478 m2 made by a single layer of Resistive Plate Counters. About 10% of the final active area ( 700 m2) is in stable operation to check the detector performance and the reconstruction algorithms. In this paper the status of the experiment and the analysis of the first data are presented.
