摘要：Range determination for K indices at Syowa Station (69°00'S, 35°39'E) is briefly discussed first, then the obtained values of K indices for about a year (from Feb. 8, 1959 to Jan. 9,1960) are tabulated. Some discussions are also given, especially on the seasonal variation of regression coefficient of K_. to K_p, which was known from correlation between X_ and K_p for the period.
