Analysis of the experimental data of joint Russian-Hungarian (FIAN and KFKI) research was carried out at Tien Shan station for the search of sources of primary cosmic rays (PCR) at energies ( E 0 = 10 14 – 10 15 eV ). Maps of extensive air shower (EAS) arrival directions are presented where the standard deviation of mean event numbers in equatorial coordinates exceeded a definite value. The excess of EAS number was observed from some directions. It was observed from an extended galactic object – the SN remnant. The young pulsar PSR 0656+14 is located near the centre of this object.
