Popis: In important and interesting papers, Freeman et al. [1963] and Frank et al. [1963] describe the first American observations of intensive streams of low-energy electrons beyond the second (outer) radiation belt. These papers also contain discussions of observations carried out in 1959 on Soviet Luniks by my colleagues and myself and of our interpretation of these observations. This gives me grounds for some remarks. In February 1960 the results of observations of low-energy electron streams beyond the second radiation belt carried out by means of the charged-particle traps on Lunik 2 were published [Gringauz et al., 1960a]. In the same publication it was noted that similar phenomena were observed on Lunik 1. In a paper [Gringauz et al., 1960b] which is cited by Freeman et al. [1963] and Frank et al. [1963], the results of measurements carried out on Lunik 1 were presented. The fact that fluxes of low-energy electrons were observed in both cases is very important, since the measurements on Lunik 2 were carried out in the direction relative to the sunearth line, essentially different from the corresponding direction of Lunik 1 (Figure 1). But Freeman et al. and Frank et al. mentioned only observations on Lunik 2, and thereby possibly gave the impression that this observation was the only one.
