TEs* HIGHEST FREQUENCY oF SPORADIC-E REFLECTIONS(MC) @ t J +i +2 +3 TIME FROM ZERO +4 (HR) Fige 3.3 ~ Highest Frequency of Sporadic-E Reflections at Rongerik following Shots 1 through 5, Compared with Normal Values. From Fig. 3.3 it is seen that the highest sporadic-5 frequencies ere decidedly above normal when first observed near_plus 1/2 hr fas absorption abated), then came very near to normal value by plus 2or3 hr. (The high value f denly attained near plus 4 hr for Shot 4 seems extraneously caused .&/ . The curve for Shot 3 is not as much above nor as long above normal as the others. This should not be surprising in view of the small relative yisld of Shot 3. The amount of datta is insvfficient to be conclusive, / Shot 5 apparently occurred ona Cay when frequencies were above normal even before the shot. 2 SECRET
