Abstract:

The nucleonic intensity observations at Thule, Greenland have established an apparently longer data base than any other station in either polar cap. During the brief period covered by this report, significant progress has been made toward understanding three important phenomena 1 the origin of transient cosmic ray intensity variation and 2 the mechanism that is responsible for producing north-south anisotropy and acceleration of relativistic cosmic rays between converging interplanetary shock waves. These results are described in detail. Author
