We have carried out a new photometric study of the remote Galactic globularcluster NGC 2419, using proprietary and archive B,V,I time-series CCDphotometry of the cluster, that allowed us to discover a large number of newvariable stars and to obtain a new colour magnitude diagram that reaches V ~26mag over a field of 50X43 square arcmin centered on NGC 2419. The new variablesinclude 39 RR Lyrae and 11 SX Phoenicis stars. The pulsation properties of thenew RR Lyrae stars confirm and strengthen the classification of NGC 2419 as anOosterhoff type II cluster.
