The cosmic-ray unusual increases of November 12 and data from the stations distributed over the world, especially in the Arctic and the Antarctic regions. The gradual rise of the 1st hump of November 12, 1960, is explained by both the geomagnetic modu1ation in the initial phase of the geomagnetic storm and the trapping of the solar cosmic ray particles by the solar magnetic cloud responsible for the geomagnetic storm. The 2nd hump on November 12 is due to the geomagnetic modulation effect in the main phase of the storm combined with the supply of low energy particles trapped by the cloud. The primary energy spectrum of the differential intensity for flare increases on November 12 is obtained as KE/sup - gamma with gamma = 6. In case of the November 15 event, the difference of the onset time in different localities suggests that the first incidence of the solar cosmic ray particles came from the direction of geomagnetic latitude 5 deg -- 30 deg S and next, about one hour later, they came from the opposite direction of 5 deg -- 30 deg N.
