The Chree method of analysis has been adopted for the analysis of the Ionization Chamber data for Huancayo, Cheltenham and Godhavn for 1946 and for the former two stations for 1945. The same procedure is adopted for the planetary index Kp also.

The cosmic ray minimum (or maximum) precedes the minimum (or maximum) of Kp by about 4–5 days. It is also observed that the relative decrease in cosmic ray intensity per day, – ΔI/(I. Δt), follows the changes in Kp in a general way, and hence the electric field as would be expected from the consideration of the theory of emission of beams of particles from the sun with the associated frozen magnetic field and the electric field arising due to polarization.
