Pagination or Media Count:
Three antennae records of E-region echoes obtained at the University of Puerto Rico in 1954 . . . 57 have been evaluated by Harnischmachers tabulation method. This is a similar fade method insofar as the drift is found from the time differences between corresponding fades on the three traces. However, these time differences are only read with a limited number of steps as entire multiples of a minimum difference, viz. 110 sec. The corresponding apparent drift direction and velocity are easily read from a table. As only that drift component is so found which is perpendicular to the fading crests, individual determinations are not considered to be significant at all. Median values of drift direction and velocity from about a dozen individual fades taken out of a period of 5 to 10 min are used as entries for the statistics presented in this report.
