Nucleonic intensities investigated during the Atlantic Expedition IQSY 1965 of RV "Meteor" (Appendix)

The nucleonic component of the cosmic rays has been measured by the German research vessel "Meteor" during the Atlantic Expedition IQSY 1965. The pressure corrected intensities fit well the rigidity calculations of Kondo and Kodamo. In this way we confirm the earth's magnetic field model used by these authors. Two positions of the cosmic ray equator have been determined at 29,7 °W (6,5 ± 1) °N and at 19 °W (7 ± 1) °N. These positions agree with the calculated values of Kondo and Kodamo. The total latitude effect of the nucleonic component amounts to 1.74 and 1.76. The measurements were carried out at solar minima activity. Using the values of latitude measurements at maxima solar activity the degree of modulation of the primary cosmic rays was determined in the rigidity range 2 - 13 GV. For rigidity values above 6 GV the modulation remains constant to 20 %.
