Abstract

The ground level cosmic-ray intensity enhancement on September 18, 1979 is analysed by combining neutron monitor data with simultaneous in situ interplanetary measurements. An explanation of the increase with respect to local acceleration process, alternate to that suggested by Agrawal and Venkatesan (1982), is given in connection with the effect of a magnetic field annihilation region.
