Abstract

A description or the equipment used in measuring cosmic ray intensities at high altitudes by both balloon and airplane is given. Results of a series or 15 balloon nights throughout the United States and Canada are discussed.

A B-29 airplane flight to Peru £or measuring the latitude effect is discussed and conclusions drawn as to the charge of the primary cosmic rays. In particular, time variations of cosmic rays at high altitude are analyzed.

A series of B-29 flights made under identical conditions expressly for the purpose of studying time variations or cosmic rays are analyzed. It is found that there is a general pattern to the variations which might be explained by the eccentricity of the sun's magnetic dipole from the sun's rotational axis.
