A preliminary analysis of cosmic‐ray neutron monitor intensity data during the November 1960 solar disturbances is presented. The first increase on November 12 is attributed to generation of particles on the sun, following a class 3+ flare. A second increase on November 12 is interpreted as the arrival at the earth of solar particles trapped in the gas cloud emitted by the sun in connection with a previous flare. It is shown that the arrival of a further cloud sweeps away the remaining solar particles. The increase on November 15 is attributed to a new generation of high‐energy particles by another class 3+ flare that occurred on the same solar active region. The characteristics of the solar flare increases are shown to agree with the conclusions of McCracken and Palmeira regarding the propagation of solar particles in interplanetary space. Data from low latitude stations are used to investigate the Forbush decreases and their relation with other solar and terrestrial events.
