The azimuthal distribution of heavy nuclei in primary cosmic radiation is measured by means of orientation-controlled nuclear emulsion stack exposed at geomagnetic latitude 24° N. Assuming that the integral energy spectrum of heavy primaries is represented by N(⩾ E) = K(1 + E)^<-γ>, the exponent γ is obtained from the azimuthal distribution comparing with geomagnetic cut off theory. The obtained value of γ is 1.26±0.35, and this result agrees with that of Kaplon et al. but not with others. This discrepancy may be interpreted as an effect of the solar activity.
