This paper presents a method of obtaining a riometer quiet day curve (QDC) of the correct shape, after modifying the technique of inflection point method proposed by R.J. ARMSTRONG et al. (Planet. Space Sci., 25,1193,1977) with Fourier analysis using computer assisted programing of the data. This me...
