Scientific paper

The MAKET-ANI detector reveals significant excess of extensive air showers with arrival directions pointed to the Monogem ring, a supernova remnant located at a distance of ~300 pc from the Sun with ~100 kyr old radio pulsar PSR B0656+14 near the center. The chances that this excess is due to the fluctuations of an isotropic flux is 2 per million. For the search of the cosmic-ray source, we use the MAKET-ANI detector data from years 1997 to 2003. The best signal bin coordinates, right ascension 7h5, declination 14° (750+14), significantly deviate from the ring morphological center, shifted in the direction of the most intensive X-ray emission from the supernova remnant's limb, now located 66 pc from the supernova remnant center and 27 pc from the candidate source.
