✦ Synopsis

The contribution to the local cosmic-ray flux from the Geminga supernova is calculated assuming shock acceleration to 1014 eV in a remnant which was formed several ld years ago along with the Gerninga pulsar. The particles am propagated to Earth using a simple diffusion model. In the region below the knee in the spectrum, it is found the supernova may contribute 10% of the local cosmic-ray flux, assuming plausible explosion parameters. The contribution to the amplitude of the anisotropy is not in conflict with the data in this energy region.

TeV energies gamma-rays, measurable by the imaging Cherenkov technique, are the most interesting for searching for hadronic CRs in SNRs because they provide information about CRs of the highest possible energies 10 13 -10 14 eV. Direct information about high-energy CR population in SNRs can be obtai
