Discovery of an intermittent pulsar: PSR J1839+15

) pairedwith a sensitivity of 0.6 mJy. The observations were carried out using the incoherentarray (IA) mode of the GMRT. The data were written to magnetic tapes. They wereextracted to network attached storage (NAS) disks of the high performance computingcluster having 64 dual core nodes. Pulsar search was done using SIGPROC† with ex-tensive RFI mitigation algorithms written by one of the authors. The trial DM rangeused for the search was 0−1200 pc-cm
