Three solar energetic proton events in the beginning of 2012 (January and March) revealed significant increases of the integral proton fluxes with energies >100 MeV were analyzed by the data from subpolar neutron monitors (>500 MeV). As it was found the event on January 27, 2012 was followed by cosmic ray enhancement of about 2% at several subpolar and high latitude neutron monitors which coincided with the onset of the intensity increase in the GOES channels. This was also confirmed with the GOES/HEPAD data that allow us to consider the event on January 27, 2012 as a Ground Level Enhancement. The events in March 2012 (7.03 and 13.03) occurred under very complicated situation in the interplanetary space and a more detailed analysis is needed. Nevertheless, these events may contain some contribution of solar cosmic rays in the ground level observations.
