The GLE of July 14, 2000 registered by the Antarctic laboratory for cosmic rays with 1-min time scale

The Antarctic Laboratory for Cosmic Rays (LARC) of the Chile/Italy long-term collaboration registered the Ground-Level Enhancement (GLE) of July 14, 2000. A report with the LARC data, based on the 5-min time scale, was published using the standard international format for GLEs (Cordaro et al., 2000a). Here we present the 1-min LARC records for the event. Moreover, we compare the LARC hourly data with the ones obtained at Los Cerrillos (LSRC, Santiago) with a multidirectional muon telescope. No clear GLE signatures are found at high energies ( > 10 GeV ). Also results from the preliminary analysis of the April 15 and 18, 2001 GLEs are shown.
